I flew 3 missions last weekend without any issues. Today I was flying again the same way. Fly the DJI GO App to the location and then switch to your App. Everything was working fine but I could not get a Homeport......Can't figure out why, it would not let me fly the mission. I got home point in the DJI App but for what ever reason could not get your App to work. I tried 5 times, from shutting down to take off until I gave up. Any ideas?
