PC and PS5 Microtransaction

Hi,

So after 1 month of email I finally was able to link my Main PS5 account to my PC account.

The thing is now that I bought All stash in both platform PC and PS5 when I choose to play my PC character on my PS5 I have all access but when trying to play my PS5 character on PC I don't have access to my stash and even my cosmetics.

I had to buy the game 1 times on PC and 2 times on PS5 because of a mistake that I made (Linking an email address to my PS5 account) I bought Warlod of the Karui on PC and King of the Faridun on PS5.

Why I don't have access to all my stash on PC when playing my PS5 character but when playing my PC character on PS5 I have access to all ?

Thanks
