FC Mobile on android asks to update, no update on Play store, game doesn't open.

TOTS finished yesterday. I opened the FC Mobile app today and was prompted to update the app with a notification. It took me to the play store but there is no update available. The game does not start just the update app notification pops up and then its loading nonstop. I have uninstalled and reinstalled the game, restarted my phone but this has not helped. How can I fix this issue
