Maybe we are not on the same page… what form URL exactly? I see on your page you have added as link “Please submit your information to be listed!” to the page. Clicking that link does work. You just have the submission for set to require a login to submit. That is why you see this message “Please login in order to submit your entry to our directory.” on the Form submit page.
Now, if you want Form and the Form link to display, you need to navigate to the Connections : Settings admin page and click the Form tab and disable the option that requires a login.
If that option was enabled, it was not the fact you could not see it on mobile, it was because you were not logged in on mobile.
Hope that helps!
PS, Also, make sure you have followed these instructions to enable the Form action link. I assume you have and this is the link that you can not see. If we’re on the same page.
