It’s not you, it’s them. On mine after a day of being out most of my ability to control devices returned 10 minutes ago.
Any attempts to control devices would return “sorry, something went wrong. Try again later” or similar.
I also received a notice on my not new phone with my 22 year old phone number that the number on my account did not match or hadn’t been registered. I verified, nope, it’s you Google, it’s you.
Have nothing other than a few tweets and mentions on Facebook as a source but going to believe it’s not me for once.
