Alexa routines are no longer being detected for the smart switches as of sometime in the last week. This happened previously and was fixed with a software patch shortly after I started a thread. This is the previous thread.

The issue is the same. I have routines set up so that when I turn the device on during certain hours, the lights are dimmed. This has been working as expected until about a week ago. I do have Alexa+ enabled, and I am not certain if they were working as expected after enabling it, but I think they had been. As of right now the routines are no longer being triggered. I'm assuming this is a bug in the Alexa skill as it was before.
