I have a Smart Controller which I am using with a Mavic 2 Pro. It has been working brilliantly up until a couple of weeks ago when the Go4 App froze and I had to start the SC again. This happened twice in a row the other day and it is a real pain in the butt. When it happens it tells me to either wait or restart. has anyone else had sim ilar problems? Also the date keeps changing resetting itself back to 2013! Help please!!
