I have read numerous articles on this issue and can’t seem to get to the bottom of it...I plug my iPhone 7 into my dji Mavic pro controller and nothing happens, I have updated everything, reset my iPhone, put in airplane mode and so on....I can connect to the drone via WiFi. I can plug in my kids iPhone 6 and theirs works fine, but my phone, when I plug in, it’s like I did nothing ....I don’t want to have to buy a new device so I can fly my drone without asking for my kids phone...any help??
