My games disappeared?

In a previous, now deleted comment, I mentioned my achievements/game history disappeared again, but it's back now. It seems to be an on and off thing, as some people mentioned that theirs disappear and then reappear again.

I'm just gonna play games, and be on the lookout if my achievements/game history disappears again.

make sure it isn’t t hidden and also check on ‘Ready to install’ tab if it’s not there I’d suggest you contact support Also be sure to have the receipt with you

If both the previous suggestions don't find the game for you, I'd recommend working with official support to review your account purchase history.

Use this link:
https://support.xbox.com/en-US/contact-us#5:0:6 If an automated assistant pops up click no thanks and scroll to the bottom. Then be sure to click "Chat with Xbox Support" or "Request a Call".

It should still be in your 'Ready to install' section.

Another user suggested that we could uninstall the app and then go to the store and install it again.

It worked for me on my laptop, but because I played during the period between the update and the fix for the update, a couple of leaderboard values are a bit strange. And all the games I played in the "dark period" between the first update and the subsequent
fix have disappeared.

My previous games have re-appeared. However, if my original opponents do not re-instal the game, they may not be able to complete our games.

I think I will message them to suggest this solution
