I'm using a Redmi Note 8 Pro.

All of the sudden all my Minecraft PE worlds disappeared.

I've tried to check the folder Android/data/com.mojang.minecraftpe/files/games/com.mojang but the minecraftWorlds folder was empty (it is empty also when a world is present, so I don't really know what is the true location of the game's files).

After swearing quite a lot for all the wasted time, I thought about the fact that my mobile phone always prompts me to "clean your device", and I probably did it in these days.

So I've tried to create a new world, clean the device using the default application (it's a function of the smartphone, I didn't use an external app), and then open Minecraft PE again... The world disappeared.

I've uploaded in the attachments the screenshot of the test I've done and so the steps to reproduce it.

Files location was set to "External" but the issue happens with "Application" too.

Looks like those of Minecraft are considered "junk" or "cache" files that can be removed with no issue.

On the web a lot of people have been reporting about deleted savegames with apparent no solution, I think this bug has absolutely priority on being fixed... I'm thinking about people who spent a lot of hours into a Minecraft world and may loose everything just with the click of a button.

Thank you.
