Store Listings page broken — cannot delete/replace screenshots or save any changes (AgentMux, Store ID 9P9QCXNNCRK3)

Question

The Store Listings page for AgentMux (Store ID: 9P9QCXNNCRK3, MSIX app) has been broken for several days. I am unable to make any changes to the listing — specifically:

• Cannot delete or replace existing screenshots
• Cannot save any changes — the save button either does nothing or returns "We are unable to save listing. Please reload the page or try again later"
• Issue persists across multiple browsers (Chrome, Edge) and in incognito/private mode
• Clearing cache does not help

All listing fields are correctly filled in. The app is live on the Microsoft Store. This is blocking a required update to the store listing.

Request: Please reset or unblock the store listing draft on the backend so I can update the screenshots and save changes.
