I am having an issue with my Sign Up Here link disappearing. It initially is showing when the app opens, but after I choose administrator or user and go to the home screen, it disappears when I get back to the page. Is there something that I am doing incorrectly? This is the first screen when I choose the view app option. Then I choose the demo_administrator. Now I am at the home screen and I am going back to the sign-in screen via appointments. Once I click appointment, the option is no longer available.
