Found this while browsing and wanted to add my two cents: have you checked if there have been any app updates or firmware updates for the M30T since your original post?
Sometimes support for new features is added in updates
You might also want to reach out directly to DJI support to see if there's a workaround or alternative solution. Curious to hear what you find out!

Although I focused on commercial pilot training with American Flyers, they offered great guidance on understanding FAA regulations, which might indirectly help troubleshoot drone compatibility. Their training is diverse and supportive. Perhaps checking settings on the DJI Pilot 2 app or reaching out to DJI support could resolve your issue with the M30T
