Need help information please if anyone has any idea what "Launcher" is. I have a Mavic 2Z and fly with the controller and CrystalSky Ultra. Last evening is the second time this happened, while flying the massage "Launcher is not responding" and gives a choice to click on "wait" or "OK". Twice I clicked on "wait", the message went away and I continued to fly. Then less than a minute and the message appeared again, so I clicked "wait", message again went away and I continued to fly. Then the message appeared a third time and I clicked "OK". Immediately the CrystalSky screen went totally black, the controller still worked, RTH worked and I landed. I found out the Crystal was still on, just no screen. The only remote information I found on the forum was to delete the Go4 app and re-install it, however the information was not the exact same scenario. Does anyone have any suggestions? If deleting Go4 and reinstalling it is a possibility could I please get directions on how to do that on the CS. Thanks in advance.
