Welcome mwf,
I understand how frustrating it can be when your Microsoft Store app submission has been stuck in the Publishing state since July 19, 2026, and that the support case you opened has already been escalated without a resolution so far.
Before proceeding, could you please confirm:
- Is this a new app submission or an update to an existing published app?
- Does the submission show any certification warnings, failed package validations, or pending actions in Partner Center?
In the meantime, you can try these steps below to troubleshoot the issue:
Option 1: Check the submission details in Partner Center
- Open the submission status page
- Review all sections for warnings, required actions, or incomplete information
Option 2: Verify submission history
- Check whether any package, store listing, or pricing updates were modified after the submission entered Publishing
Option 3: Review Partner Center notifications
- Check the Action Center and registered contact email address for any requests from the certification team.
Option 4: Create a new support request update
- Reply to the existing support ticket.
- Reference the submission ID and indicate that the submission has remained in Publishing since July 19, 2026.
I hope the steps above help you deal with your issue.
