Put the summary of the bug you're having here; I just updated my minecraft game on my iPhone, and ever since that the furnace in survival mode hasn't worked, it will let me put whatever I want to smelt but it won't let me take it out or put anything in as fuel it won't even let me tap the bottom square. Since this isn't working I can't play the game and I have spent more than £5.00 on this game. It's a bit upsetting.

What I expected to happen was...: being to use the furnace in survival mode
Describe what you thought should happen here; I thought that I should be able to smelt materials

What actually happened was...: won't let me put in a fuel to burn the material or take the smelting block out
Describe what happened here
I put in a cobblestone block to smelt into stone but it won't let me put in fuel or take the cobblestone block

*Steps to Reproduce:Put a step by step guide on how to trigger the bug here
1. ...collect 8 cobblestone blocks
2. ...make a furnace
3. ... Put cobblestone in the first square of the furnance
4. ... Tap the second square and nothing happens, so I can't smelt anything
