Hello, I have one problem with my app dji go, I can not connect it to the Rc.
What I can do?
I have a dji phantom 3 advanced

Join the crowd.  You can forget getting it to connect with the Camera view till DJI or Apple come up with solution.  Trust me, I've tried everything that's been suggested with no results.  I have an Iphone 6s.  Don't waste your time resetting your phone and all that stuff.  It's a firmware problem

Hello malteita7777, did you try to use other lightning cables or reset your device to factory via iTunes?

I've seen an iPhone camera image come to life after just unplugging lightning cable and then putting back again, with DJI GO running.
Might be a quick fix until other settings/software can be resolved.
