Well it doesn’t seem to affect Windows 10 and iOS, if I switch the difficulty from peaceful to normal, the mobs don’t disappear. I tested version 1.19.20. I also tested every kind of mob you would see everyday in your Minecraft(animals, villagers, fish, etc). Since this issue affects Android(according to the bug report), can any users that use android test if this bug reproduces in their world too? I don’t use android so I have no idea.

Hostile mobs won't be affected by this bug since if the difficulty is peaceful, hostile mobs(except for a few) won't spawn and despawn immediately as soon as the chunk the mob is on, is loaded. 

Let's say that if the creator of this bug report mixed up and actually, mobs disappear if the game difficulty is switched from normal to peaceful, it will still not be an issue since, as I said, once the game difficulty is set to peaceful, mobs(except for a few) despawn immediately as soon as the chunk the mob is on, is loaded, if you set the game difficulty back to normal, the hostile mobs(in the night) will slowly spawn back.
