Has anyone run into issues using the draw portion of the Go 4 app?  I purchased the Apple because Android wasn't supported or offered for the GS Pro app.  I've  had the Go 4 app crash several times while I was flying and using the "draw" function.  The support folks only suggested re-installing the app or trying on another device.  I shouldn't have to try another device especially when the Apple was the only option for the Ground Station app.  I found it pretty absurd to even suggest trying it on another device after spending $400  for the Apple.  Has anyone encountered this issue, and if so, have you found any solutions?  

I finally received error reportinginstructions  from DJI, but I was hoping this problem was already addressed
Thanks in advance, Craig

Hello Craig, could you please clarify which Apple device you are using?
Please connect your mobile device to itools and export the crash log then upload it to dropbox and send me the link.
I'll forward the log to our engineers for review.
