az provider register -n Microsoft.App stuck in "Registering" for 2+ days #34214
Description
Describe the bug
The Microsoft.App resource provider has been stuck in "Registering" state on
my pay-as-you-go subscription for more than 2 days. It never reaches
"Registered". Other providers (Microsoft.ResourceHealth,
Microsoft.OperationalInsights, Microsoft.Insights) register fine on the same
subscription. Portal shows: "'Register' operation check timed out on Resource
Provider 'microsoft.app'". This blocks Azure Container Apps / Flex Consumption
VNet deployments. I have a Basic support plan, so I cannot open a technical
support ticket (billing case 2610120050002174 was closed). This looks like a
backend issue that needs a registration reset. Could you route it to the right
team?

Bug Analysis
The reported two-day
Registeringstate and matching Portal timeout point to ARM/Microsoft.App service-side registration, rather than an established CLI defect. This is based on the report and source review; I have not reproduced the issue or diagnosed the backend root cause.The command mapping routes
showto the provider GET operation. The registration implementation submits registration to ARM and reads the service-returned state.--waitonly polls that state every 10 seconds; it cannot repair or reset a stuck registration.Next action: the existing ARM/component owners should route this to the Microsoft.App registration/service owners to inspect the affected subscription through an approved private channel. Please keep subscription identifiers, authorization credentials, and debug secrets out of public comments. This evidence does not establish a CLI change or promise a backend reset.
