You created a new team linked to your FB. Your device team can only be opened on the device it began. On that device, try logging out the FB team:

1. On your phone application, navigate to the Settings tab
2. Select Log out
The application will automatically redirect you on the log in page, which should give you the option to connect via Facebook or Let me play.

If the "let me play" still isn't there make sure there is no Facebook app or service running and try again.

If this doesn't work please ask at No, I still cannot find my team. | TopEleven Support
