My P4 Pro Plus screen is locked asking for me to register on the DJI sign in page. I enter my address and password, but it says no internect connection available. How can I get out of this page and reset the internet connection? I've tried doing a master reset- holding C1, C2, and the record button at the same time. It beeps once, then continues to beep until I turn it off. I'm not sure how I got here, and I definitely don't know how to get out of this... any help would be greatly appreciated!
