It sounds like you're experiencing a frustrating issue with the Microsoft 365 Developer Center dashboard. Since you've already tried several troubleshooting steps like changing browsers, clearing cache and cookies, and testing on another device, here are a few additional suggestions:
- Check for Service Outages: Sometimes, the issue might be on Microsoft's end. Check the Microsoft 365 service health status to see if there are any ongoing issues that might be affecting the dashboard.
- Account Permissions: Ensure that your account has the correct permissions and is properly set up in the Microsoft Entra tenant. If you're part of multiple tenants, make sure you're accessing the correct one.
- Contact Support: If the problem persists, it may be necessary to contact Microsoft support for assistance with your account and potential sandbox provisioning issues. They can provide more specific help regarding your account setup.
Unfortunately, I cannot verify your account or make changes to your tenant directly. Please reach out to Microsoft support for further assistance.
