Tbf, people have been complaining about the lack of Shared Stash ever since PlugY compatibility was nuked.
Tbh, I can live without Shared Stash as long as there are plenty of local Stash/Inventory pages (I don't really trade items among characters anyway. I just like collecting stuff). Yeah, Shared Stash is a nice feature. But being able to play without constantly worrying about all your progress being lost due save file corruption, which could happen at any time, is nicer.
