Premium Stash upgrade purchase did not work

Hey there,

Are you able to attempt logging out of the game client, then back in and opening the microtransaction store? This should help refresh any purchases you've made.

There may also be some confusion as premium stash tabs are the same size as standard stash tabs, but will have extra features such as the ability to name the tab, change the colour, and list items on the trade website directly from your premium tab.

I hope this helps!
