I am experiencing the same issue! Except on an iPhone (app version is 5.35.0 which based on the app store, is the latest version as of a month ago).
I can only connect to the app when I am at home. This started happening after the system updated (I was trying to set my alarm and it starting lighting up in a circle, I went to the app and it said “updating”) and then I was away from home and saw the same message as the screenshot posted here.
I have left my house again and was unable to connect to anything in the app when not home.
When I manually disconnect from WiFi, I experience this issue. This has NEVER been an issue before as I am able to use the app (and other apps) when I am not connected to WiFi.
