Was just about to add my pearls of wisdom to encourage a fellow mumsnetter on the brink of giving up smoking and couldn't as I couldn't see what I was typing. It sort of scrolled up too far so I couldn't see what I was typing and the keyboard. This, a new thread, seems fine so it was just the commenting that was a problem.
I am on an iPhone using the app. I may of course just be being a muppet ..... Anyone else having the same problem?
