Hi @bfinn19
By default, after turning on Coming Soon mode of the plugin, it shows Coming Soon page for all general site visitors on all pages of your site.
Also you have more settings to adjust Coming Soon mode to be seen or not for specific pages or users. In the case you have followed the instruction above, logged out from the site admin area, and still can’t see the Coming Soon page, please provide the page link on your site. Thus I can see what’s wrong and help you.
