App functionality is closely connected with your theme HTML structure, so we did our best to test it on different themes, but there's always a chance that yours one has some unique elements that will require a bit custom setup.
Nevertheless, I'm pretty sure will be able to make it work perfectly on your Store. Please grant me access to your Store Admin so I may investigate. You may send invitation to firstname.lastname@example.org. Please also send us an email to that address explaining your problem.
