Dynamic Light on Android

Hello!I did an endless runner on the UE4, but on a real device, dynamic shadows from directional lights are not displayed. Everything works in the editor (DX11 and ES3.1). All spawn objects in game are moveble. I used different options for the light and shadow settings. Switched between forward and deferred rendering. Made the light stationary or moving. I turned the skylight on and off. Includes cascading and modular shadows. I think I’ve tried almost every combination of lights and shadows in the engine, but couldn’t get dynamic shadows to work on a real device (tested on 2 devices). I couldn’t find a solution on the internet… After a week of testing, I decided to ask a question here. How to enable dynamic shadows for Android? Is this even possible? Maybe mobile shadows worked better in the old version of the engine?
