I just went throught this, I discovered they moved it smart home vs devices like they had it before. I had mine set up with good morning/night and a few other routines like off 3am just in case one falls asleep watching TV. Everything still works like before just have re add it to routines via smart home now.
This happen to me overnight last night 10/14/2019 was working fine when we went to bed and this morning getting error message that she cannot connect to TV check network connection and power. But everything is working.
