Problem with adding rep

I'm using site on mobile so not sure if that's the problem.

But every time for the last week when I try to rep people it keeps saying something about minimum of 10 characters. I'm trying to write way over 20 char nothing works. Keeps giving me an error

works fine for me famalam
try writing 500 words (not joking)
