I have the Mavic Pro.  A few weeks ago, I purchased the iPhone 8Plus, and now my Mavic Pro will not connect to it.  I previosly had the Mavic Pro connected to the iPhone 6, and never had a problem connectioning to my Mavic.

Does anyone know how to overcome this problem and have my iPhone 8Plus connect to the Mavic Pro?  Thanks.

Did you try the full USB port with a stand Lightning cable. That used to work before I upgraded to IOS 11.2 beta 2.

I just got my iPhone 8+ yesterday (but am keeping my iPhone 6 for my Mavic- just in case).  Anyway, my 8+ works nicely with the Mavic.  I don't know if you saw all the posts about the cable, but several said that the phone connecting cable that came with your drone is of poor quality.  The folks, like me, who have reported success are using an iPhone cable that plugs into the remote's USB port (located just below where the phone mounts on the remote).  I had previously bought a 12 inches long one, so it connects my Mavic and iPhone8 AND is short enough to not be a bother.

Hi, please try to update your iPhone's firmware to the latest version and see if it work. It issue persists, please unplug the side cable and try your original lightning cable. Let me know if steps above doesn't work.

My iPhone 8 Plus works just fine with the stock DJI cable
