did not receive my Xbox Gamepass perks for PSO2 PC

The perks for PSO2 should work on the Windows store version as well as the Xbox version, as they the Xbox play anywhere versions of the game. If you are playing from some other store such as Steam or Gog, then the perks will not work.

Hi, im in the United States. I purchase AC with a US bank accoint with a US address.

You need to check if this specific perk are available to your region.

I hope the PSO2 perks come back soon.

Same issue. I got game pass ultimate just for the pso2 perk. First the perk never showed up for pso2. Checking daily it finally showed. I claimed it. Went in game ans nothing. I contacted pso2 support amd they guided me to their website. Its a free game
however, i have spent money. I understand when things are new and have problems but clearly there is something wrong and nobody knows the answer. The perk says i have till april 16th. But to do what? Ive claimed it and its not showing in game. I got someone
else to play amd they got theirs. Super frustrating. Someone just give me my perk!!!
