I faced serious problem trying to launch mavic 2 pro in non-fly zone. I have also crystal sky with dji go 4.3.16 app. Internet connection was up via mobile phone.  When i triet to start propelers self unlcking slider apeared so i slide it. Next was a warning window so i tap 'yes'. Next apeared white, square window with an X in left corner (close winodw) and nothing happend next. The window stays blank even after a few minutes. And I cannot fly. Before i bought crystal sku i flew this zone using andorid tablet and it worked well.

Is this a bug in DJI Go crystal Sky version?
