Cloud saves don't work at all.

This problem has gone on for about a week now. Each time I enter (Screenshot1.png) or exit (Screenshot2.png) I get an error as shown in the screenshots. I've tried all the recommendations given in previous posts with similar situations, such as, clearing the cache, reinstalling the app, repairing the game, reinstalling the game, but nothing worked. In fact, I reinstalled windows just yesterday and I still get the same error messages on my new fresh install.
