Same problem here. So much for having a simple interface for my senior
father-in-law lol yet another disappointing Google showing. Just shipped
back my new Pixel Tablet. What a disappointment that was.
I am having similar problem. Unable to add or edit routines. It's very
random as I can add a few devices and yet others that are the exact same
brand cannot be added. Or edited.
I am having the same problem with a lot of bulbs. Some of the same brand
can be added while others can. Very random. I think it is an issue on
Google's side with recent changes as all of these worked fine until just
the last few days.
