Issues with Microsoft Teams Admin Center and Setup for App Development

Question

I’m developing a Teams app that includes a bot and personal tab. I followed the documentation and completed the following setup:

Steps Taken:

Microsoft Azure:

• Created an Azure account.
  • Registered an app.
    • Added a custom domain (bondu.io) and added 3 users.
      • Assigned full admin permissions to one user.
        • Set up a default subscription (assumed free).
          • Created a resource group.
          Microsoft Developer Program:

          - Joined the Microsoft Developer Program and filled in the required details.
          
          **Microsoft 365 Admin Center:**
          
             - Verified that the users show up in the user list, but they are listed as **unlicensed**.
          

1. Microsoft Teams Admin Center:
   • When I log into the Teams Admin Center, the login succeeds. However, I receive the following error: *Internal calls to PLS Service have failed. We can't find the tenant region for my-tenant-id. Please try again later.*

Issues and Questions:

Teams Admin Center Error:

• How can I resolve the error regarding the PLS service and tenant region?
  • Is this a known issue, and should I wait or perform additional setup steps?
  Licensing in Microsoft 365 Admin Center:

  - Do the users need any specific licenses for the development/testing of Teams apps?
  
     - If yes, which licenses should I assign, and how can I obtain them through the developer program?
  
     **Platform Access and Management:**
  
        - My use case requires managing the app through the Teams Developer Portal and the Teams Admin Center. Is there any other configuration I need to complete for smooth access to both portals?
  

Please guide me on resolving the above issues and confirm if I missed any important setup steps.

Teams Admin Center Error**

The error message Internal calls to PLS Service have failed. We can't find the tenant region for my-tenant-id. Please try again later. is a known issue that can occur when the Teams service is not included in the user's subscription. Here are some steps you can take to resolve this:

1. Check Subscription: Ensure that your users are in a plan that includes Microsoft Teams. You can verify this by checking the subscription details in the Microsoft 365 Admin Center.
2. Bug Confirmation: If the issue persists, it might be a bug in the tenant. Microsoft has acknowledged this issue and is working on a code fix. You may need to wait for the fix to be deployed.

Licensing in Microsoft 365 Admin Center

For development and testing of Teams apps, users typically need specific licenses. Here are the steps to ensure your users have the necessary licenses:

Platform Access and Management

To manage your app through the Teams Developer Portal and the Teams Admin Center, ensure the following configurations:

1. Teams Developer Portal: This is the primary tool for configuring, distributing, and managing your Microsoft Teams apps. You can register a new app, import an existing app, and manage app configurations.

2. Teams Admin Center: Ensure that you have the necessary permissions to access and manage apps in the Teams Admin Center. You can allow or block specific apps and configure app settings.

2. Go to Teams apps > Manage apps.
3. In the upper-right corner of the Manage apps page, select Actions dropdown menu > Org-wide app settings.
4. Under Custom apps, turn on the Let users interact with custom apps in preview toggle and select Save. https://learn.microsoft.com/en-us/microsoftteams/platform/m365-apps/prerequisites
