An Azure service that provides a general-purpose, serverless container platform.
Microsoft.App usually finishes registering within a few minutes, so 90 minutes stuck at "Registering" means something is blocking it in the background. Running the register command again won't move it along, so it's better to find out why it's stuck.
- In the portal, open your subscription > Activity log, filter on the last few hours and look for a "Register Subscription" or provider registration event that failed. Open it and check the error in the JSON tab.
- Under the subscription's Policy > Assignments, check whether any policy denies resource provider registration or restricts which providers or regions can be used. An org-level policy can quietly block this.
- Make sure the account running the command has Owner or Contributor on the subscription, since registering needs the
resourceproviders/register/actionpermission. - If the Activity log shows nothing useful, open a support request. Provider registration falls under subscription management, which doesn't need a paid support plan. Include the namespace (Microsoft.App) and the times of your attempts.
Is this a new subscription, or one that's part of a company or school tenant with policies applied?
If this resolved your issue, please consider accepting it as the answer. If the Activity log shows an error you're not sure about, let me know and I'll be happy to keep helping.
