Can't post review from android phone?

I have tried a few times to post reviews on my android phone now, but every time - an error appears and Folksy won’t allow me to submit it. I can only do it from my laptop, which is a bit of a pain and means it’s more likely I might forget to leave one as I rarely use it now. Also means that it makes it harder for customers to leave reviews, which is never a good thing! Something I’m doing wrong or a general issue?
