The game detects either my rooted device and/or tools such as GameGuardian so I can't use the unsigned .apk to login with GP. The signed version doesn't work either, because as soon as I've logged in with Apple, the game is stuck in the "Setting up login method" screen forever. Restarted multimple times and logged in multiple times.
