Same here. It looks like it wasn't designed for any kind of device. I'm on PC now and will most likely be kicked out in 3, 2, 1 ....before I can even reply to this message.
I've tried on iPad and it's absolutely dreadful. It took me nearly 40 minutes yesterday to share a simple comment. It was as though the entire forum was screaming at me. I inwardly yelled back at it, as to not frighten the neighbors.
I'm not even logged in on phone, mainly because I will probably crush it in my hand out of frustration. I occasionally read on it though, and it is equally terrible.
