I Can't delete the assets form the store listings in Microsoft Partner Center for my App BITSWAP on Microsoft Store.

Subject: Cannot delete or replace Store display images – “Failed to delete asset”

App: BitSwap (Store ID 9NK6C4JBFBQC), Submission 4, Store listings (English).

When I click the delete icon on the existing Store display images (1:1 App tile icon 300x300, 150x150, 71x71, and 9:16 Poster art), I get “Failed to delete asset. Please reload the page or try again later.” Because the old images can’t be removed, I can’t upload the new ones.

I’ve tried reloading the page, other browsers and private windows, and waiting several hours. The issue persists. Screenshot attached.

Please let me know how to replace them.
