Hi there, I can certainly understand your frustration. After completing the verification and account linking process once, it's not unreasonable to expect to be able to jump straight into the game the next time you play.
What you're describing isn't the intended experience, so we'd like to gather a bit more information to better understand what's happening. When you launch the game, are you being asked to sign in to your EA Account and complete email or phone verification every time, or is there a specific step in the process that keeps repeating?
If you can provide a few more details, we'll do our best to point you in the right direction.
