Unable to Access Guild Stash Tab After Purchase and Quest Completion

Dear Support Team,

I recently purchased a Guild Stash Tab in the game using my account, and I have already completed the quest "Treasures of Utzaal" in Act 3 with the character I’m using.

However, when I try to access the guild stash, I still receive the message:

"Complete the quest 'Treasures of Utzaal' in Act 3 to access the feature."

I’ve attached a screenshot for your reference.

Could you please help me confirm whether this is a known issue, or if there are any additional steps I need to take to activate the feature? I would appreciate your assistance in resolving this.

Thank you very much for your support!

Known issue with the new Socketables tab in Guild stash that as of yet has no fix, to my knowledge.
