We have a feature request for adding a true "load more" button for infinite scrolling views, and it is gaining traction for an upcoming release. Do you have a staging site set up where we can temporarily deactivate some other plugins and activate a default theme to run additional tests?
For some reason, admin-ajax.php requests are being redirected to the dashboard page when the User is logged out. I haven't been able to pin it down to some specific cause yet. Any ideas? I'm still investigating.
