No, you are NOT playing with Beta team, you will be playing with your real club if you log in with the same account. If you don't want to play a lot of friendlies (not want your players to be tired a lot), you can always watch someone else's matches
When you install Beta, the standard TE app that you already have on your phone will not be deleted. So, whenever you want to play the one without animated Live Match, you can do it![]()
