If it's showing as active, please let me know if you're using Windows 10 or 11 and we can proceed to further troubleshooting.

Ultimate is just a bundled subscription of Gold, Game Pass for console, and Game Pass for PC. It doesn't change what games are available on Game Pass. Doom Eternal is available with Game Pass for PC.

Game Pass Ultimate doesn't have a separate PC or console version. Only the standard version of Game Pass does. Game Pass Ultimate includes both Game Pass for PC and console as well as a Gold subscription.

If you already have EA Play (or standard Game Pass/Gold), it'll be converted to Ultimate as well.

Yes.

Game Pass Ultimate is just a bundled subscription of Gold, Game Pass for console, and Game Pass for PC. It doesn't change what's available through Game Pass.

Game Pass Ultimate is only a bundled subscription of Gold, Game Pass for console, and Game Pass for PC. It doesn't change what games are available on each platform. Game Pass for PC doesn't have the same amount of games as Game Pass for console, so you won't see all of the same games on the PC.
