I went to hell and back trying to solve this problem for my son. For whatever reason, madden 21 or EA or whoever is very sensitive when it comes to minors playing this game (IF) they are under 13 years of age. The only fix to this problem is to log in as the family manager account. Then go to Family management in settings and create a new user. Make sure that you create the account as an "Adult Account" and make sure the age you enter is at least 13 years or older. I just put the birth date in as 2000 to be safe. Once you create this new account, all of these problems will go away. Just know you will have to go to gmail and create a new gmail email for this new user. It was a total pain in the arse but this works.
