when i open the game on my ps4 it never loads its always stuck on a screen that says minecraft and has a bar the goes barely half way and never loads. ive sat there for 3 hrs and it still did not load. 

New 1/9/2020 I figured a way to bypass it. so u need to uninstall the game from system and reinstall it. once i did that i haven't had problems since. PS your worlds should still be there mine were. also i was the one who made this report and fixed issue myself. tell me if u did it and it works
