I would send a request to Nordeus Support for help with that.

Since the original Team is attached to your phone, keep in mind it's not as conveniently portable as the one attached to FB (which can be logged into on many machines)

To get to the one on the phone you could try deleting the app's saved data and stopping all facebook processes and then try opening the T11 app, but Support might have a better answer. They work normal business hours, and season start is busy, so give them time to answer.
