Unable to connect saved flt missions on Mission Hub with Litchi App on IPad. I would appreciate anyone with steps to accomplish would post. Have tried DJI Flt planner (clunky, disfuntional at best). Is I-Funbox the only app that will download the flt to the Litchi App? Do I need to remove the DJI Go 4 & DJI Go Fromm the IPad?
