Are you certain that your files are not on the internal storage?I have used Litchi for the first time yesterday. I manually started recording before flight and received an aural and visual confirmation that the app was recording to the Mavic Pro 2 on my smart controller. I had auto record off and no instructions at each waypoint as I was using waypoints with curves so thought that would suffice....... No Files at all.
Tried using GO4 app to test capture card and all was perfect.
Contacted Litchi support but no response so far. Trawling through the manual but no explanation as yet.
Basically the drone flew a perfect profile using Litchi but did not record anything despite showing an active record icon on the controller, quite strange.
