This sounds like the same exact thing that happened to a few of my GE ZWave (not plus) switches.
The device appears online
The device reports status
The device will not activate from the ZWave network
Local control of the device works
This is being reported a few times in the community on different devices… In my case I had to exclude and re-add the switches. Support appeared to help another user in this thread:
Including @Kianoosh_Karami who helped that user.
