Buttons in settings don’t work – Knitting Chart Review

I just paid a fair amount of money for the full app on my phone thinking it would connect to my iPad. I tried to restore the app in the settings menu, but none of the buttons work. The website doesn’t work either, so no way to get in touch with the developers. I liked the app the first time I used it, but don’t want to pay twice to be able to work on a brioche pattern.
