I have to repair my controller to Drone every time I fly it because I am now getting "lost signal". I have deleted and reinstalled app and nothing. I get it all ready to fly, app up and all (camera viewfinder visible) gimbal even works flawless but I have one flashing bar on the controller signal. Repair it and perfect the entire flight..... switch out batteries and I have to do it again... any suggestions? It happened after I reset my phone... and now it happens with my tablet too. (Drone has been on 1.6.8 with no issues) did they update the app past two days?
