Regardless of what device you are running the GO app from, the txt file needed is located here:
"DJI/dji.pilot/FlightRecord"
Once you open the FlightRecord folder, scroll towards the bottom to locate the flight you want help with. That file will look similar to this:
"DJIFlightRecord_2016-08-23_[19-22-40].txt"
When you select the Browse... button from the
www.phantomhelp.com website, it is the similar looking file mentioned above that you are searching for. Which again is located in the:
"DJI/dji.pilot/FlightRecord" folder.
