cant find list of xbox 360 games iown

You can actually go onto an xbox 360 console and from the guide i think it is on the far right and there is a purchase history there. And since you are on an xbox 360, it won't show you non-360 titles.

Not sure where you can find it online anymore.

It won't be sorted by anything other than date of purchase and it'll include things like demo's, themes and avatars.

by going to account.xbox.com and then going my games and it used to bring you to a page that list all of the games you own sorted by xbox one, xbox 360 and pc but now am not able to browse my xbox 360 digital catalog as xbox 360 button is missing ... any
other way to see all my digital xbox 360 games i own

log out of xbox one try to power cycle your console. Please hold down the power button on the front of the console for approximately 15 seconds until the power light shuts off. Wait about 60 seconds, then power it back on. Be sure you see the green "XBOX
ONE" animation loading screen when you power it back up. an then log in and go to game i own in menu

If the 360 titles you own digital are part of the back compat programm you will find them in the ready to install section in my games and apps on your xbox one. Normally you should get them aswell on your Microsoft Account page. If you still got an 360
you could try to get that Info there aswell.

My Game Is in that list, but I cant find It in Xbox app, it's forza Horizon 5
