Zombies breaking down Iron Doors

I noticed this bug too but in Bedrock not Java. Simple solution for now till its fixed. Place a wooden door sideways so that when its placed it appears to be open. The door will work normally but because when you close it it's technically open, zombies can't break it down as they think they should be able to walk through it

Thank you for your report.

Is this still an issue in the current version? If so, please update the report or comment and it will automatically reopen.
