Anyone else having trouble accessing the game via game sharing on an Xbox? My son is a sub account under me and is unable to get in since the new season released. Never had an issue before that.

Message from SoT support below. If you are having an issue let them know so hopefully they can fix it quickly. "Following our initial investigation, this issue is appearing to be related to Xbox Live accounts which are accessing Sea of Thieves via Game Share. So at this time, only the account which owns your copy of Sea of Thieves or the Game Pass on your console will be able to enter the game though we can confirm that this issue is being actively investigated further with a view to resolve soon."
