oh, I voted, wrote a really long comment and then it asked me to log in via steemconnect, and I did, but then once it connected it just reloaded the poll, looks like it didn't record my vote. I will do it again but figured useful to know if your testing the app :)
EDit: Re-did it, signed in via steemconnect first, and it worked, so i think you may need to log in before it prompts you to, as if you wait until it gives you the option, it loses your comment/vote
