Changes to the news reactions?

Have there been any revisions to the news page in the last few weeks?
I can’t post reactions using my iphone. More to the point, I can’t get the iphone to recognise that the reaction box is somewhere I can type something.

Previously, about 3 weeks ago, this worked ok.

Any constructive suggestions?
“Don’t use iphone” is not constructive.

I’m using safari & myfox1.5.
