Greetings,
My MAG322 just upgraded to 2.20.07r3-324 of Dec 10, 2018.
And now I have the problem of a blank preview screen also.
On the 2.20.07r2-324 version it worked just fine.
Could you please post an official solution to this?
Thanks a million
SOLUTION: A RESET TO FACTORY SETTINGS solves the problem (even after a hard reboot the preview is still working fine)
