There is a bug with Kickoff Celebration Season. When you click on a team to start the season, the game crashes. I have tried it on multiple devices.

It did work for me. Uninstall Madden mobile 20 then reinstall it. Again make sure your account is synced to the services I mentioned. If you are playing as a guest your data "might" still be linked to your device. I think the only way to lose your game data is if you changed devices entirely. That I wouldn't recommend though.
