I did not see any server issues or issues with the game, so if its not your connection.

1. Did your game update, verify the files and simply log back into your goggle or apple account.
2. Contact their bug-support page on discord. See if anyone has the same issue.

3. Check your drivers and system see if that needed anything updated.

Sounds like the game may need to update, you can also try unloading the game as a last resort, Once loaded back up, simply again log into your account.

See if any of that helps. If that did not help, contact them.
