Alexa routines triggered by Alexa contact sensors sometimes would stop working.
I have investigated this in great details and found a case where it may stop working.
I just made a fix to this. At this time, it should be working for everyone. Time will tell if the fix is successful.
Please let me know if it stops working for you.
If anyone still had problems with routines, please give it another try.
A bug was found and fixed earlier today. Accounts with no preferred ISY would not receive events.
The Alexa skill can work with no preferred ISY if the account only has one ISY. However, events would not be sent in that case. Now they are sent in that case as well.
