Solution to start the game immediately without waiting and without black screen.

Maybe some already know, others not.
I do not know why the lack of information on this subject, inside the game itself but ....
Do not start the game without appearing the green light at the top right.
Only when the green light appearing ,you can click ready ,and the game starts immediately without waiting.
If you guys now, of any other basic information like this ,please inform the community, if it is not too much to ask.
Not get how ,or wy ,Uber not fix this information yet.
This and really basic info that no one seems care to show.
For me this always work without any problem now.

Most players already do this. Black screens and other glitches are still common even when waiting for the green light.

I think at the time they made the tutorial it wasn't in yet.
it's just the way things turned out. a better tutorial is comming down the line.
