Air2S and smart controller question for those who use this combo. Has any one had issues where the Dji fly app just shuts down mid flight? 3 times now I have gotten the “Dji Fly app has stopped” while I am in the air. Never had this issue with the RCN1 controller with my iPhone or iPad mini 6. Truly regretting this purchase so far. All firmware is current as is the Dji fly app. Any help, suggestions or otherwise?
