Hi can someone help me ! I have an iPhone 6s with the latest software I can't connect to phantom 3 professional, also I am unable to edit any footage recordings in the DGI App on mini iPad but i am able to operate the phantom 3 when trying to save it, it continuously shows 0% outgoing and it fails to save.

Try deleting the app and reinstalling.  Also try different lightning cords.  

I've been having the same issue for weeks now. DJI haven't been any help at all. They told me to restore my phone to factory settings, although I had already done this. It doesn't work. The lighting cable isn't the issue either. Im 99.99% sure it's a bug in the latest firmware for the Remote Control. It connects to the aircraft it's fine, but there is no signal from the RC to the iPhone through the Go app. So bug.
