Sorry about that! If you are in the wrong team, there are two places to change it.
Just go to settings (the little wheel above the green dice at the top of the menu page) or to the ranking pages and make the appropriate correction.
We rely on recent IPs to set the teams. A limited number of users will now be in the wrong team. We can only apologize for that. There was no easy way to make this perfect.
Thanks for letting us know!
