How can i redeem my Game pass Ultimate perks after moving regions?

I understand, but I already have the Game pass Ultimate and its active.

The perks are for Game Pass Ultimate subscribers. If you no longer have the subscription, then you are not eligible for the perks. If you want them, you will have to subscribe to ultimate.

You can claim the perks by logging in on Xbox beta app on windows 10, the game pass app on mobile device or log in on your xbox one console, and find the perks on there and claim them. Each perk gives instructions on how to claim.

I was double checking.
Lithuania is not a supported region for Xbox game pass ultimate
https://www.xbox.com/regions

This is why you’re not able to see the perks.

Just as a friendly reminder, please note that bypassing geographical restrictions to purchase or redeem content not available in your country can lead to an account closure

For the game pass perks, it is per perks and not per subscription.

For example, I have redeemed a code perks for World of Tanks, after I redeemed it, I will not be able to redeem it again even if my susbcritpion expired and renewed.
