Today was a bad day at the flying field I was at taking pics and vids of a funfly event. Needless to say I didn't get much flying it because every time I tried to take a pic or record video the Dji Go4 app crashed on my Smart Controller. I tried reloading the firmware today and within 30 seconds the app crashed again. I have heard that you can clear the Cache but I am wondering if I will lose anything doing that? Maybe I have a setting that is off or on causing this but I am completely lost.
