My game says its not out yet when it is

You may need to get in contact with support here and hopefully they can find the problem from their end.

I deleted the game and reinstalled it works fine for me now try that fix

A common issue these days. We all are waiting for a solution. I contacted devs. No answer as jet. You can try it too. Another thing, you can install an insider hub app and report a problem from your console.

this seems to be happening to a few people recently.

are you part of the Xbox Insiders Program? some of the other people experiencing this are in the Insider Program so that could be a contributing factor, if you are.

did you buy Outer Wilds from the Xbox store or did you get it as a Mixpot Reward for watching the E3 show on Mixer? that seems to be another link between those who are having the same issue.

I know this isn't a lot of help but at least you know the problem isn't at your end.

So I got the game Outer Wilds from watching E3 on mixer. I've played it and it worked fine. Then I stopped playing it for a couple of months, and now when I try to play it, it says the game isn't out yet. Any way to fix it or are other people having the
same problem as me?

Was it a beta copy
