I had the same problem some weeks ago and a friend of mine some days ago.
I encountered an issue today...
I was caching in a somewhat remote area with no cell reception. I had offline data so I was fine. Then the app stopped working with an error message that looked like it was trying to connect to a login page. Reseting the app brought it right back to that page too. When I got back to wifi it wanted be to login again (to refresh a token?) and then it was fine.
I understand how the app needs to check in and refresh the token, but is there a way to his can be scheduled or controlled?
