Game Pass

Did you buy standard Game Pass for console or Game Pass Ultimate? EA Play is only included with Game Pass Ultimate or PC Game Pass, not the standard Game Pass for console.

Also, if you purchase Game Pass first, then it would be converted to Ultimate and if you cancel ultimate, you would lose your Game Pass subscription. So if you do cancel Ultimate, do it first before you downgrade to just Game Pass.

Which subscription are you downgrading to, is it Xbox Game Pass, PC Game Pass, or Game Pass Core?

If Game Pass Core, you will only have access to just over 30 games that are part of the Game Pass catalogue, and online multiplayer.

If Xbox Game Pass, you will have access to all the Game Pass games on the Xbox Console, and no online multiplayer.

If PC Game Pass, then you will have access to all the Game Pass games on the PC including EA Play, and online multiplayer.

Game Pass Ultimate is just a bundled subscription of Gold, Game Pass, and Game Pass for PC. So games downloaded from Game Pass will work the same as they do with standard Game Pass versus Ultimate.

Since Forza is a Play Anywhere title, you an download it on both the PC and console without needing Game Pass for PC or Game Pass Ultimate.

If you're signed into the same account, then you're still using Game Pass Ultimate. Game Pass Utlimate is just a bundled subscription of Game Pass for console, PC Game Pass, and Gold. It doesn't change what games are available with Game Pass. So on the PC, you would still have access to the same Game Pass games with Ultimate or standard PC Game Pass.

Just to verify, did you purchase just regular Game Pass or Game Pass Ultimate? If it's just regular Game Pass, makes sure you bought Game Pass for PC, not Game Pass for console.
