My son registered for the Infinite flight before the deadline, downloaded the xbox insider hub, but when he follows the button to download it at the micrsoft store, the store only says “not available.” This is on the xbox s. Any ideas? I tried to leave the preview but an error message comes up that I can’t do that because it is under a different account. This is the only account he has, and it matches the invite email he was sent. Has any one else had this? Any suggestions or fixes? Thanks.
