Hopefully, someone will have a solution. Problem:
1. 12.9” iPad Pro 3rd generation will not connect to RC. If I restart the IPad, it will connect with camera view…etc. But, if I power everything off and start over, IPad will not connect. I do the hard restart and it’s hit and miss the next several attempts. Bottom line, I have connected to the IPad by doing a hard restart, but not able to every time. I have also deleted the app and reinstalled several times…no luck.
2. I borrowed another IPad 12.9” (5th generation) and it worked flawlessly.
Really struggling with this as I want to use this IPad (12.9” 3rd generation) for flying. Any insights would be greatly appreciated. Thanks.

Try cleaning the port on the IPad. There is probably some crud in there preventing  a good connection.

Thanks for the info.  Thing is, I’ve been using an ipad with various DJI drones for the past 5 years w/o any problems at all.  In fact, I’ve never lost connection with the other iPads.  I can also connect to a different iPad Pro 12.9” (5th edition) w/o issues.  Just wondering why this is the only ipad (Pro 12.9” 3rd edition) that won’t connect.  Using my iPhone is just too small.  Again, thanks for the info.

Update: I have a mavic 2 and 2S. The 2S still will not connect to the iPad Pro 12.9 (3rd generation) but will connect to the Mavic 2. Therefore, I assume the port on the IPad is ok and cable is also good. Only conclusion I can come up with is that DJI changed something in the 2S remote that will not allow it to link to the iPad Pro. Thoughts??
