Urgent: Teams app publishing process blocked - app does not appear in the store after approval

Hello Michael, your analysis is correct: the incident MO1093370 on the Microsoft 365 Service Health page is likely the root cause of your issue. When there is a service degradation affecting Teams infrastructure, app publishing, discovery, and update propagation can be delayed or blocked—even if uploads and releases appear successful in the Developer Portal and Admin Center.

Monitor the Service Health Dashboard for updates on MO1093370. Once Microsoft resolves the incident, app publishing and discovery should return to normal.

There is a direct connection between your publishing issue and the ongoing service degradation. Once Microsoft resolves MO1093370, your app should appear as expected. No action on your side is likely to resolve this until the incident is closed.
