Brand new to DJI; bought a P4 refurb and it looks immaculate. Getting ready to get everything setup, but I can't even complete my profile in the app because it crashes every single time I try to set the country/region. Really surprised; makes me wonder if it will crash while in flight. Anybody else have this problem and know how to fix it?

I have an iPhone 6s Plus by the way.

What's the current version of your APP and mobile OS? Have you tried to re-install the APP?
