Seems glitchy; cant get past 1st screen

I was excited to try this app but on the first screen it asks me for my first name, I enter it and nothing happens. The help button doesnt work. I tried typing, talking, and hitting enter on my keyboard but nothing seems to get me past that first form field of the first account creation screen. Please troubleshoot this! Id like to use this app. Im on an iPhone 7 Plus running iOS 10.3.2
