Edit 11/7/2017: OKAY, update is out! Voatify v1.0.5 update fixes this bug. Comment away boys! (and girls!)
We've found out that the latest iOS update (11.0.3) will break the comment box. Sort of. It works, but it's a little funky.
When you try to make a comment in a thread the first time, everything will be fine. But after you post or cancel your comment, any subsequent attempts to comment will make the comment text box not shift correctly, making the keyboard covering the screen.
However, the commenting still works. You can type your comment, but you won't be able to see what you're typing. After you are finished, you can tap anywhere off the keyboard to close the keyboard, and then press the Send button to send the comment.
It's a pain in the butt, but that's what the latest update did to the app. It will take about 2 weeks to get an update onto the App Store if it can be fixed in a timely manner. You can follow this thread for updates. I'll be posting here when it is fixed!
*Edit (10/23/2017): So the comment boxes have been fixed...however, with the new iOS update, it added a whole new mess of problems! Currently trying to figure them out one by one. They are just really small annoying things like the Subverse titles not be touchable, and the names not loading right. Might need another week or so to figure these out.
Edit (10/30/2017): Okay, everything is fixed! Will be submitting to App Store soon to version 1.0.5 to fix this bug. Should be live in another week at most, by 11/7/2017.
