Good morning. I found something that, so far, has worked for me. After numerous uninstalls/reinstalls, logout/login attempts, etc., here's what worked for me [knock on wood]. On the DJI GO App I logged out, and while still on the screen that prompted me to login, I powered off my iPhone. Then I powered up my iPhone and went to the GO app which immediately prompted me to login BUT in addition to username and password it required a verification code after typing it in it took me to the GO app home screen. I got the green light to fly and flew it about 200 feet up and out and repeated it. I didn't want to fly any further today as it is windy, but I really wanted to resolve this issue. Let me know if it works for any of you drone drivers.
