I have added 2 accounts to my family pack and I am having trouble adding the last account. Whenever I put in all the information, I get to the point where it asks [insert name here], do you want to join this family?... I select Yes but then an error pops up saying "Can't sign in using your Microsoft account. Please try again. If the problem continues, go to https://account.live.com. I followed that link and the account signed in fine there but it is still not allowing me to add the account to my family pack. I have deleted and redownloaded the gamertag profile multiple times but this issue keeps popping up.
