Whether it's user error or not, I can't be sure but I had 44 Hubitat devices linked to Google Home but the App has disappeared in Hubitat and the Nest Hubs are telling be that Hubitat is unavailable.
I went and clicked 'reconnect' in the Google Home App but it errors so the other option is to unlink and start again (I'd rather not have to assign rooms to all 44 again).
I'm guessing that restoring a backup of the Hub may not work either because it's a cloud authorization?
Any tips?
