I have followed the normal steps to make the enter dragon respawn and it isn't working for me. I have been able to do this before, so I am not sure what I am doing wring here. I am playing the PlayStation 4 version of Minecraft.
This is common if you kill the dragon and then update the game. The new patches invalidate some things that prevents you from being able to spawn the dragon a second time. If you want to fight the dragon again, you need to use the "reset the end" option from the world settings. This will allow you to fight the ender dragon again and unless the game gets another update, allow you to respawn it as normal.
