I have an inspire 1 pro and use an Ipad Pro tablet with it and it has worked ok for the past year with some issues here and there but now the app has been crashing during flights for the past month and now it wont even open. Any ideas?

Probably fault of iOS 11.x.x.  My iPad Pro 10.5" often disconnects too at times, but it hasn't crashed as the disconnect is more frequent for me.  I can unplug and replug the USB cable and usually get it back....for a while.

If you go to the Apple forums, a lot who use their Apple device to hook into their car's stereo system are having troubles too with the USB.   Google "CarPlay iOS 11 USB" for their connection and crashing horror stories.

Hi, sir. Please follow the advice above. I would recommend you update the IOS system to the latest firmware. Please install the latest version of app. Also, please ensure that there is enough memory for your Ipad to run the DJI GO. I would not recommend you expose your Ipad under the sun. Thanks for your support.
