It was the room where you need to place a bomb next to a switch and quickly run past the barrier before the bomb explodes. I had figured that was how to continue through, but no matter how many bombs I placed on or near the switch it wasn't setting the switch off. It eventually worked but seemed random. So when I left the comment I assumed it was broken or perhaps bombs couldn't set off the switches. Now I understand they can, but I went back to try to replicate the issue and I did have issues with the bombs not setting off the switch, sometimes even if the bomb was directly on top of the switch.
