it seems the issue is with loading old account either through Facebook or through Game Center.
Delete the app. Reinstall the app. Start up as a new account. Then on top left hit menu and accounts. Log out of the guest account. Then you can log back into your Game Center or Facebook account!
Did you try the workaround step that @joedepo provided above?
iOS Mobile Troubleshooting
Hey @EA_Blueberry thanks for reaching out.
Yeah, I followed all the steps in the troubleshooting guide.
I can play if I create a new account, but that's not what I want, I have a legacy account connected with my Facebook account that I have been using since the game launched a few seasons ago, and I want to keep playing with this one instead of creating a new account.
Every time I reinstall the app and try to login using the Facebook option, it crashes and I need to uninstall it to be able to try again.
Any ideas on how to fix it or other options that I could try?
Thank you agian.
