MSIX submission stuck in "Publishing" for 5 days – support form fails with EHCT4001

App: Belong Coach Companion (MSIX)

Store ID: 9NPWFMNS0WLZ

Issue

Submission 10 passed certification on 10/28/2026 and has shown "Update in publishing" since then (5+ days).

The changes from Submission 10 (parental-control info and in-app purchases notice) are already visible on the live Store listing, but Partner Center still shows the submission as "Publishing". Because of this, I cannot cancel it or create a new submission.

Support form is broken for my account

I tried to open a support case through every available route:

• Partner Center → Partner AI Assistant → "To raise a support ticket, click here"
• developer.microsoft.com/windows/support → Create support case (MSA)

All of them open Engage Center, which fails with:

EHCT4001 Sfb does not exist or user context does not have permissions to it

operationIds:

• a64a6481a77950a42c4baddd69eecec3
• 5d9665c6db837d5a5960d4cce311aeda
• 4ced599f82f558feaabad1e949f71a9b

I'm signed in with the account that owns the developer account (personal Microsoft account), the same account in both Partner Center and Engage Center. I tried Chrome and Edge InPrivate with the same result.

Request

Could a moderator please escalate this so the stuck submission is completed or reset, and the support form issue is looked at?

Thank you.
