So,,I am using Litchi App, with a Phantom 3S, and my mobile is an iPad mini 4. 1. Love Waypoint., 2. TROUBLES with Track: as soon as I switch to Track and get a green square onscreen,..if I move either way, Litchi loses the Target!! I hear a voice, "target lost due to lack of confidence", or "target lost due to lack of optimum conditions". This happens even in perfectly still conditions., 3. TROUBLES with Track and Follow: exact thing happens as above. HELP, PLEASE.
