iOS 11.1 is what came with my new 128GB iPad
MIni 4 from AT&T. DJI GO 4, which is NOT the latest version, is now super-stable following uninstall/reinstall. I'm afraid to upgrade either the DJI or the Apple software because DJI Assistant 2 does not work for me, which means I could not roll back to a previous version of DJI if necessary. After I've signed into DJI, the Assistant asks me to put a code into a Verification box. The DJI rep advised me to uninstall/reinstall the software but doing so accomplished nothing. I really do miss the maps, but I'm terrified of going back to repeated crashes.
