I have not had this happen in the last 12 months of ownership of a CS 7.85 (not UB) and quite frankly would be telling DJI if it had crashed. Forking over what we do for these monitors, one would expect performance.
Un-nerving to watch an iPad over heat and shut down but a CS in Flight !!!
Have you received any reply from DJI on this?
(Bad enough if you want to stream you have to go back to the iPad)
