Azure Communication Services WhatsApp display name review pending for several days and Copilot Studio cannot detect the account

We are running a DEV proof of concept using Azure Communication Services Advanced Messaging for WhatsApp and Copilot Studio.

The WhatsApp channel was created successfully with a separate DEV phone number. The number is not connected to another BSP or WhatsApp provider. The channel is visible in the ACS resource, but its status has remained “Display name review pending” and is now “Syncing” for several days.

Because of that status, Copilot Studio can select the Azure subscription and ACS resource but displays: “No WhatsApp accounts are associated with the selected Azure Communication Services resource,” so the WhatsApp channel cannot be deployed to the agent.

Event Grid delivery and the internal Copilot Studio → Power Automate → Dataverse flow have already been tested successfully. The only remaining blocker is the Meta display-name approval / ACS channel availability in Copilot Studio.

Is there a supported way to escalate or refresh a WhatsApp display-name review or channel synchronization that remains pending for several days, without deleting or recreating the existing ACS channel?

No production WhatsApp number or existing provider integration has been modified.
