Welcome Jon Hill,
Thank you for explaining what happened. I understand you were given a case number and a link to reconnect after the download completed, but the link now shows “service request is closed.”
If that service request has already been closed, please start a new contact with Microsoft Support and providing your existing ticket number.
Once the ticket number is shared, the new support agent should be able to review the notes and case history associated with your previous interactions. This allows them to continue investigating the issue from the current stage rather than starting from the beginning, which can help reduce the need to repeat troubleshooting steps that have already been completed.
I appreciate your patience and understand the time and effort you have already invested in resolving this issue.
