I found this thread on the mavicpilots group, lets you convert the litchi file to one useable with say the mini 4 etc
This is the correct link:
“Litchi Waypoint Mission to Mavic 3 Waypoint Mission converter” by @wesbarris
and
“Litchi Mission Utilities” by @wesbarris
Yes but the link has a bit more information about the tool with instructions etc, something missing from the webpage
Lots of hoops to jump through. And does not guarantee a full conversion
