I am making quite a huge game for a while, but until this week I have not encountered this problem. After the splash screen there is an interval about 5 - 20 seconds, where the screen is just black and nothing happens. Only after that, the main scene starts. This happens on Android build as well as on .exe version.
Do you have any piece of advice?
I am using Unity 5.6.1f1 (cannot use the newest version because of some assets that I need…)
