I cant redeem my code for PC game pass and PC game pass ultimate

I didn't buy Game Pass Ultimate, I redeemed a code for regular game pass on PC and yes I am using the same login

As long as you're signed into the same account you used to redeem the code, then it'll automatically be on the console when you sign in unless you redeemed a code for PC Game Pass and not console or Game Pass Ultimate.

If the code itself was for Xbox Game Pass, then it would have been redeemed as Xbox Game Pass regardless of where you redeemed it. There would be no way to redeem it as Game Pass for PC.

The only way it would have converted to something else is if you have Game Pass Ultimate (which includes both Game Pass for console and Game Pass for PC). If that is the case, then it's not possible to revert it back to what it was before being converted.

If the code itself states it is for the console and you don't have Ultimate, you would want to contact the retailer you purchased it from and see if there is anything they can do since it is the wrong card.

I haven't had ultimate but I had normal game pass for pc before

That would be why you can't redeem it then...from the FAQs in the link I posted before:

"If you were previously subscribed or currently subscribed to Xbox Game Pass for PC, or an Xbox Game Pass Ultimate subscription, you will not be able to redeem the two month trial for Xbox Game Pass Ultimate!"

No code for Game Pass (console/pc/ultimate) is automatically redeemed to your account. Microsoft and Xbox gift cards from Rewards are added to your account automatically, but game pass is not.
