Please double-check the following:
1. Ensure a stable connection.
2. Make sure your Facebook/Apple ID account and password are correct.
If you come across the "Invalid access token" prompt while re-connecting your Facebook/Apple ID account, it is because you're connecting a Facebook/Apple ID account different from the initial one. If so, reinstall the game and try connecting the Facebook/Apple ID account you used initially.
