Game pass is not letting me play games that I own on disc

So the games i own and see the issue in is gta V , rainbow six siege , black ops two , minecraft , ect. Two of those i own on disc and the other one digitally and whenever i put the disc in and get into the game it like ad walls me with game pass like forcing me to try and buy it when i already own the game . My live pass is still good , also when i try and play some of those games i cant even play offline or online it doesnt let me do anything i just get like ad walled by the game pass

It still let's me play the games, I have game pass ultimate, none of the game I have installed are disc games,

Same, it has the same triangle on most of my games which I bought with my own money. The games ain't from game sharing or game pass

I had game pass awhile back and I played games that I owned on disc through gamepass instead of inserting the disc. After game pass expired my disc games and digital games still work. Have you tried uninstalling and reinstalling the games? Are you getting
a message saying do you own this game? Insert disc to play. Or is your xbox just not reading the disc at all?

Did he actually purchase the game or was he playing through Game Pass? The game was just removed from Game Pass, so you have to own the game in order to continue playing. If he owns it on disc, make sure the disc is in the drive.

You still need the disc to play the game because it is with the disc that you prove you own the game. If the disc is readable it will work for sure.

Let me know how it goes.
