Launcher flashes between connected and not connected and shows this error: We were unable to verify what products you own. Please check your internet connection.

Trying to follow Microsoft's solution to this issue did not work. Reinstalled launcher, and now it says "Buy Now" instead of "Play". 

If I open the Xbox app, it says "Xbox services are having issues."

Others are having this issue too. I see multiple other duplicate issues. My friend is able to play on the server I have up and running, so it seems isolated to certain people.

There are also issue going on at the Xbox website. Says something went wrong when trying to view my profile.
