Replicated, thanks.
It looks like something changed in the recent iOS update, the app is trying to push the user to login but can not launch the view so it restarts at Home Tab. 
I don't yet have a fix and can only test on the emulator as I left my iPhone cable at home. Please try to disable WiFi and Cell network which should give you time to get to the Account Settings before refresh.  Finally re-enable the Mobile Device's network and login.
If the refresh happens before you can login, remove the Account (trash icon) from UDM on UDM's Account screen.  Then go to the Controller's settings and login when prompted.
I'll push an update as soon as I can verify a fix, but could be 24 - 48 hours before approved by Apple.

This may happen if the app is deleted or app data is cleared, the new instance of the app creates a new Device.  Apple does not let this persists or transfer between apps/devices.  If you have a screenshot taken before changing the enabled value, or remember, the "Updated" timestamps it may give some clues.  Could have happened recently or long ago, the former could be the cause of your issues using Notification Groups as the "new" device needs to be added to the group.
Click the Mobile Device in the list and there should be a delete option at the top.

Yes,  eventually the Home tab will only show devices and scenes as multiple controllers will be in the controller dropdown header.

This was removed as we had too many ticket where users hide the controller from themselves.  However the most recent version on both Android and iOS now automatically show the default (last selected) controller on the home screen.

If this is no/null status then it is likely disabled in settings.

I cannot replicate, however I notice that the strike through the equals-sign is not easy to see.   Which screen has this issue?

That's not good...I'll push a fix now to correct the issue.  Depending on Apple's review could be a few hours or days until live.

Thanks for the report, will be fixed in 1.1.67 iOS and 1.1.87 Android.

This is a bug in the AC, and will be fixed in an upcoming update.  If there are missing IDs (in sequential order) in Notification Customizations then only the Customizations before the missing IDs are shown.  As a temporary fix add Placeholder Customizations to fill in the missing numbers.  When adding a new Customization it should be assigned the lowest possible ID, do this until all missing IDs are added. 
UD Mobile should work without placeholders.

Replicated, will be fixed in iOS 1.1.66
Thanks

The command is sent immediately, however a value update is not received immediately which may appear as sluggish.  Showing the estimated new value before receiving a value update is on my list, but no time frame.
UDM limited the dropdowns to ~200 values so this makes sense if the thermostat has a precision/step of 0.1.   Can you try to change the Step value in the editor to "1.0" instead of "0.1".  See the Missing Widget example for instructions to get to the editor https://wiki.universal-devices.com/index.php?title=UD_Mobile#Missing_Widget.
If this does not work, or the instructions are not clear enough do to UI changes, please send me a copy of the UDM backup file and I will take a look.  Please point me to the location of this node if it is not at root Home Tab or Favorites tab.

If that was your device, please try version 1.1.86, it may be a few hours before live in the Play Store..assuming the holiday does not delay the app review.

Sync has not been changed in some time so I'm not sure what would cause this error.  Please open a ticket and include UUID and we can run a remote diagnostic.  Also include a zipped copy of the UDM backup file so I can investigate the blank page when pressing the home button.
The app now automatically shows the last selected  (if you have multiple controllers) Controller's Devices and Scenes Folder.  There is nothing else to show here as  programs/vars/etc are now in the automations tab.  If using multiple controllers they can now be switched via dropdown instead of backing out to the list of controllers.
The Controller's icon can be changed in the Controller Settings click the menu next to the controller name.  Users can also add their own image via the URL option.
This should show a list of controllers, please include a zipped copy of the UDM backup in your ticket
Programs, Variables, and network resources are now in the Automations Tab.  Feedback from users showed most usually open Devices and Scenes if not using Favorites, so this removes a few button clicks.
Aside from moving some Home tab items to the Automations Tab, most of the changes are settings moved into menus or dropdowns  

4.x to 5.x upgrade resets username/password to admin/admin

We are in the process of a revamp, so things may move around in the next few versions.  It should be on Home Tab Menu for now.

Will push a new version to beta later today or tomorrow which should correct the issue.

Thanks,  replicated issue.  Submitting version 1.1.79 now.

There is no real way to toggle a program, as the commands which handle running programs are runIf, runThen, runElse, and Stop.  UDM emulates the a program toggle by sending runIf (if not running) or sending stop (if running then/else).  So On is "running" and Off is "stopped".
As a work around an integer variable as boolean (0=false | 1=true) status can be created.  Enable the current program then set the variables boolean value in the then and else conditions. Create another disabled program which is triggered by UDM which has an if condition using the variable. The original program can still be used as the Display Status if needed.

Not yet, We have other PG3 fixes close to the top of our list so will look into at the same time.

It looks like status is not being populated so UDM cannot determine which direction (on/off) to toggle.  Pressing the tile when there is no status should take the user to the "Device Dashboard" which forces a query for status, after this point the app can toggle.  However it is very likely that status was missing because UDM is not receiving status updates for the device so it may not reflect the current state.
What is your eisy firmware?  If it is less than 5.8.3 please upgrade as there issues with remote connections on some previous versions.

Yes, If it is not 5.8.3 try upgrading first as there was an issue with remote connections in earlier versions. 

Thanks but I do have one. The issue is time as the flex device I have is connected to a serial cable and would take time to reset then reconfigure for serial connections after testing.
I the new version does not work please attach the Node Server's Log.

Please test the following to help narrow the issue.
Is this only favorites or Home Tab also?
If Both:
Does the Admin Console show the variable update if it value is change from UDM?
If it does:
With Favorites open showing the variable(s), does UDM show variable update if value is changed from the Admin Console?

Not currently.  As an alternative you could send yourself a notification if the garage door is left open for some time after you leave the geofence. Although It would require opening the app to close the door.

Issue found and corrected.  This may require delete all notifications as some users had duplicates.
