Donated to guild - bought quad stash tab - gone

With PoE2 on Geforce Now I donated 185 to my guild and bought a Quad Stash tab. Guild balance is now zero, but there is no Quad Stash tab.

Please support.

Same here.

I had the same problem, and found a solution.
I tried to send 185 points to the guild then buy some storage space.
Points are gone on my account but nothing happened.

My guild leader passed ownership of the guild to me, not sure if this is important.
After clicking the buy guild stash storage again, I got the option to open some guild settings in a webbrowser. The aforementioned Link opened this:

There, I was able view guild transactions and accept the 185 points. Then I switched back to the game, and then, when trying to build the same storage space with 185 points, there was a confirm button. That enabled the storage space in guild stash.
