What if I bought a game with the gamepass discount, when I cancel the subscription do I...

You keep anything you purchase. You will still need at least Game Pass Core to play it online though.

You purchased gamepass and then canceled your Xbox live. Now you want to cancel gamepass so then when the subscription times run out you will no londer have either gamepass or live. You canceled both.

I do not see any store refunding you for a subscription you bought, activated then canceled.

As long as your gamepass is active, games that are in the gamepass will run in that section. If you purchased the game seperatly it will work after your subscription is not longer active. Stuff you bought with the discount is your to keep and will work
afterwards too. The only thing you cant use anymore after your subscription is canceled are games you dont purchased and the discounts you get for the addons or games. So dont worry about the games and dlc you already bought. Hope that answers your questions.

When you say you "bought with Gamepass", do you mean you purchased it using your GamePass discount, or you're installing it using GamePass?

I have Gamepass, and I bought Ultimate with the discount
