DJI Knowledge quiz error.: I get a message saying to take a quiz when I load DJI Go 4 but then I when I say ok it says Error and nothing appears. Then it says I have 4 chances remaining to take the quiz before I get locked out. I am connected to the Internet. I have updated all firmware on drone and controller and batteries and I have the latest version 4.3.42 installed. There are dozens of messages about this at your forum but no one seem to have a fix. What is the fix?

Hi there. Thank you for reaching out. Please try to uninstall and reinstall the app on your mobile device to see if the issue persists, all the DJI files must be deleted on your mobile device before you install it again. Please note to sync your flight records to avoid being deleted before uninstalling. Please keep us posted. Thank you for your support!
