Not sure if this is intended behavior, but version 1.4.7 of the app only opens favorites on App Launch. It USED to go back to favorites when you toggled back to the app from somewhere else.

Restarting phone does not help.

Running this on an iPhone.

The process has changed as the automatic change to Favorites causes issues in some processes if the user leaves or the app directs user to a webpage.

New process is listed here: https://wiki.universal-devices.com/index.php?title=UD_Mobile#Show_Favorites_at_launch
