I have followed this tutorial to create a witch farm in Minecraft PE version 1.2.0.9 on Windows 10: https://www.youtube.com/watch?v=hZnIzDW6rU0&list=PL_wF24XB3qewTrXTQvDq_WZdt8yVUGeXO&index=14

All nearby caves are lit up and the area around the farm is flooded to ensure no other mobs are spawning, and I waited the correct horizontal distance from the witch hut however no witches have spawned. I noticed this has been an issue previously but those bugs are marked as resolved. Is it intentional for mob spawns to work differently than the Java version? Will this affect the spawn rates on Xbox One and the Switch once those are converted to Minecraft PE?
