Huge difference between PIE and Launch mode

Hi there, I’m an UE beginner and I came across difficulties while launching the game on launch mode. While my PIE version looks preety good (pic 1 was taken right after light building), the same level launched on android nougat (SDK 24) looks totally different- it has got messed lightning and shadows, also the courtain (visible on both pic’s) looks strange.

LEVEL LIGHTNING INFO:
-directional light: (movable, Intensity: 9.0, Indirect lightning intensity: 6)
-skylight: (movable, Intensity: 0.18, Indirect lightning intensity: 6)
-lightmass: (world settings- pic3)
-PostProcessVolume: (I use some of it’s features, but I think this is not a problem)

PLEASE HELP!

PS
my android settings:
minimum SDK: 19
target SDK: 21

PPS
red LIGHTNING REBUILD note can be ommited, as it refferes to a different scene in this level
