My R/C will not recognize my iPhone X OS 11.2.2.  I was informed by support they DJI doesn’t support my device.  Anyone been able to use their iPhone X.  Has to be a way.  
Last firmware update was awhile ago.  With a Samsung Edge.

P3 advanced
R/C model: GL300B

The latest GO 4 app update was supposed to fix the problems with the X.

I use DJI GO app could be the difference.

I use DJI GO app.  Just read it will be fixed in the next update. I’ll just keep waiting.

Hi, can you connect the drone to your Samsung Edge? Please try and confirm. Btw, you can also try to reinstall the DJI GO app on your iPhone X, remember to do a backup like syncing the flight record and saving the pics and videos before your reinstallation or change another connecting cable. If it doesn't help, please kindly wait for the next update as you can see the note on the latest app update, iPhone X will be supported in the next update. Thank you for your patience.
