Cross Platform Stash Tab Availability

Long time PC player with lots of stash tabs etc.
Made my character on PC and then switched to PS5 and all of my premium tabs are "Remove Only" when I access my stash on PS5.
I was very excited about being able to play the same character across platforms, but this would probably be a deal breaker if premium stash tabs are not automatically shared.

Is this intended?

Sony stated you have to purchase everything via the PS5 and can’t cross buy, so it works fine for Xbox but with PS5, you have to buy everything again including MTX if you want to use them.
