DJI GO 4 app doesn's support the iPhone X screen, it leaves 2 big bars on each side and doesn't take up the whole screen.

I have an 8+ and no problem (I know the 8+ and the X are quite different).   Others using the 8 and 8+ found that their connection problems were solved when they started using a cable with a lightening plug to the phone and a USB connector to the remote.  There's a USB connector on the remote just below where the phone mounts.  

Hey, sorry to hear, but I can only wish I had an iPhone X to have a problem with!  ;-)

Iphone X is such a new model and the fully test has not been finished. The request has been forwarded to our engineers for review. Thanks for your attention.

i hope it will be added soon. Shouldnt be much work to edi the UI to go around the notch a bit.

When viewing a 360 panorama in  R mode with iPhone X there is still two big bars at the top and bottom of the screen that take up a large part of the view with VR Goggles  do we know when this will be fixed?
