I guess all of us?. It is just not very stable App. It happens to me even when taking photos. I get this message: Connection lost and option if I want to initialize RTH or cancel. But I have full control of the drone all the time. So I just press cancel and wait untill GO4 comes back to life. It interrupts the video recording though.
Thank you for both replies. One colleagues told me he has only received that msg once...Yesterday was a first time for me..a bit unsettling: The message says: "Unfortunately Go4App has crashed....or something like that." I did NOT lose flight capability but as I fly over ships and water, its a bit unnerving.
This morning I followed some advice I found: CLEAR CACHE. As I have two Crystal Sky monitors, I've temporarily swapped one for the other. Ran vid recording for 2 minutes in living room and played back vid from monitor and no crash. That's a change. About to go test fly in my local park. Shooting stills, this doesn't happen to me. Hmmm. Will report after my test flight. And thank you for this community. Jonathan in Bronx, NY.
