Two days ago I was flying my Mavic Pro over St. Augustine beach. As has been happening since the Spark was introduced, the DJI GO 4 app crashed midflight. The problem was that when I restarted the app, the battery on the Mavic was low and went into the RTH mode. This would normally be ok, but this time I noticed the home point was over the ocean, where the drone was located when the app restarted. If I hadn't paused the flight and manually flown the Mavic over the beach and landed it, the RTH would have landed it in the ocean. I am appealing to DJI to fix the crashing issue on the DJI GO 4 app as soon as possible!
