Does anyone else have this issue please?

I have recently re-registered with different email through a different search engine because Mumsnet was freezing and slowing everything down on my iPhone.

But now I am having the wierd issue that, when I type an answer out, beyond a certain number of lines, the blue line at the base of the posting area, with “Active” , “Watching” , “My feed” etc, gets in the way of where I am typing if that makes sense, so you have to keep pushing the posting box up, but even then, I am having to type without seeing the words appear on the screen. Then I stop typing and roll the screen up to see it!

Really strange! Is this designed to keep posts short? Or am I doing something stupid?

Thanks for any info!
