Unable to provision Communication Service: There was an issue accessing storage, please ensure defaultRollout has completed.

Question

Background: Last week, I created a Communication Service and was unable to find any local phone numbers that could receive SMS. I deleted the resource. Today, I tried to create another Communication Service to see if phone numbers have become available.

When I attempt to create the Communication Service, I receive this error on Resource Name: Error during resource name validation. [object Object].

Digging into my browser's network inspector, I see InternalServerError Possible reasons: There was an issue accessing storage, please ensure defaultRollout has completed. If it has, please create reach out to RPaaS team: 'aka.ms/rpaas-getting-help'. (That URL leads me to an authentication error about an app not being installed in my directory; I'm guessing it's obsolete.)

And idea why I can't provision a Communication Service?
