Sea of Thieves Team Working to Address Closed Beta Error

Update: The "too early" error should now be resolved for "most" players, while "remaining cases should be resolved within the next 2 hours," according to the Sea of Thieves Twitter account.
"Anyone who digitally pre-orders in the next 24hrs will need to pick up the Closed Beta through the Xbox Insider Hub on Xbox One and/or Windows 10," reads a subsequent tweet. "This will resolve the issue entirely."
