Experiencing issues with accessing a Microsoft 365 E5 developer Sandbox subscription after changing the phone. The Microsoft Authenticator app reset, and now unable to log in. After entering the password, it prompts for the authenticator code, which cannot be retrieved. Customer Support has not provided a solution. Is there a way to resolve this issue or is there dedicated support available for Microsoft 365 E5 developer Sandbox subscriptions?

Once you lose access to your Microsoft Authenticator and don’t have backup methods (like SMS or email), you’re locked out, and Microsoft 365 Developer Sandboxes do not have dedicated or priority support, they are considered non-production accounts with limited support options.
