Look at your video,
Brave Guy,
Here he stated it showed the card, I didn't go toward a formatting problem if the card shows up in the app.
Can not record with my p3 4k
Rod
in that video it shows the troubleshooting i did to try a resolving the issue, i also show a part when i put the firmware on the memory card and it keep making the beep sound but the light on the gimbal stays green; when i check the internet that light should flash green and red.
