Whenever I try and load up Ps4 edition Minecraft on my PlayStation, it becomes extremely buggy. It's been like this ever since you released the "Cross Platform" update, along with 1.15. The main issue is that whenever you try to load up a new world, it just says "Failed to create world,". Even when you go back to the "Old Version" (As, there is a button for that.) You still CAN load up a world, and you can play it. But, after closing Minecraft and re-opening it, the world is gone from "Your Worlds".
