Just released today.  No Mention of the DJI Quiz Challenge Fix Though.

https://forum.dji.com/thread-182593-1-1.html

I have updated to this version. I updated through DJI Assistant 2 For Mavic.  
Date:        2019.03.01
Smart Controller Firmware:        v01.00.1400
Updated the built-in DJI GO 4 to v4.3.14

Once completed, I Opened and closed DJI Go 4 a dozen times and have NOT received the Quiz Challenge yet.  Fingers crossed.

Can't wait to get home tonight and update!  Fingers crossed as well.  I wonder if they totally removed the quiz requirement?  I received an email last night from DJI tech support and they asked me to turn on the controller and mavic and check for the quiz.  Unfortunately the darn quiz message popped up right away.

FYI... Nothing for the M2ED crowd!

DJI Gamora,
Can you confirm that this bug has been fixed? I am speaking about the "Knowledge Quiz" Error on the Smart Controllers.

I started mine with no quiz screen this morning. Did the updates through Wi-Fi and like Fazmanicg, I have not had the quiz screen.
Wonderful feeling. I will look forward to Sunday for my first flight with it.

Then I hope they removed the requirement to take the quiz until it is finally fixed.  Thanks for your quick response.
