Cross progression pc&ps5

So I bought the 200 pack on PC along with some tabs. All the premium stuff is unavailable on ps5. I would have assumed this is account level. If not, I guess I could work around it, but am I expected to buy stash tabs per platform? I mean that's some ubisoft level money grubbing. I am hoping that this is, at least not gonna be the case on full release.

Yes I bought the base level for ps5 but the accounts are properly linked and my toons are there and playable.
