Google Home, device "isn't available right now"

All the sudden my Google Home can no longer turn of a smart outlet named “TV”. It will just say “It looks like the TV isn’t available right now”. It says the same thing for other smartthings switches? Anyone have any ideas? I reauthorized access to the ST devices, but no change.

The firmware update was rescheduled for today. Maybe some other update???!

Same problem. Can’t get Google Home to do anything with SmartThings. It authorized and worked fine for over a week, then suddenly thinks nothing is available.

Disconnecting the SmartThings hub from my network for a bit and then reconnecting fixed it for me.

I have the same issue. Do you know how to solve the problem?
