Hi Everybody,
since unity 5.4 my apps take about five minutes to load when the app is splitted where it was about 10 sec with Unity 5.3, have you got the same problem ?
Please help 
Marc
Same problem here. The issue started with 5.4 version. Now the scene load takes 5 minutes! (in 5.3.x, it tooks just seconds). If the split option is disabled, all runs ok.
