Two of my Games have disappeared and say I no longer own them.

Were the games on the console when you bought it or did they come as a code? Consoles don't come with games pre-loaded, they would have had to be redeemed on an account. If you're not using the account that redeemed the codes, you wouldn't own the games. In that case, you would need to buy the games in order to own them.

Hello, 5STARR5859. Thanks for reaching out! My name is Lucas, and I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

When did it start to happen? I ask because two days ago Xbox had a major server issue which affected everything from buying/downloading games and DLCs, games asking to be purchased again, payments being refused.

Their servers are still getting back to normal and some users are complaining they're still having issues. Would you please wait a few hours to see if things get back to normal again?

If problem still persists after a few hours, please let me know on what device you're playing.

Probably the server issue is causing it.
But if it doesn't get better just let me know and I'll help you out

Thank you! I only just noticed the problem today, so it may be likely that the server issue is the cause of this. If it doesn’t fix itself in a couple days, I’ll see what else I can do.

The problem is games disappear out of installed and ready to install on my xbox all the time and i constantly have to go find them in the store and hit “Install” so that it adds back to my tabs. And its not like it doesnt know if i own it cause its says
“install”, not “buy”, some games just disappear randomly.
