Well I've just deleted my DJI Go 3 versions. There should be no need to hold onto both. I'm hoping that the Go 4 version will have had its code optimised to run at its best.

Both DJI GO and DJI GO 4 support Phantom 4, you can just keep DJI GO 4 as Aardvark said in your iPad since you use it most.
Thanks Natalia, when the iPads a 16 gig..space counts...cheers
