POE 2 stash tabs

Hello, i bought the game TWICE, once on PC, second time on ps5.
Since i got 300 points additionally for buying it again, i decided to buy some stash tabs.
i had no damn clue they are going to become totally useless on PC, where i play way more, and to be fair, the PS5 version is UNPLAYABLE in endgame, literally 10 fps while mapping. Played for 15 mins and turned it off.
What about my stash tabs GGG, im not going to be able to utilize them normally on my PC and i just wasted ~30 euro?
If i just wasted 30 euros for stash tabs that are "premium" to my ps5, then its a goodbye GGG.

also the game is barely playable on a 9800x3d+5080 PC, often drops to ~40-50 ish fps while mapping, and don't get me started about playing with someone, we played with brother and his fps were in the 1-10 on a 7600 and mine around 40 when we both started casting.
How can you release something like this and ask money for it.
How do you make ARPG game run worse than path traced cyberpunk?
