Pop Over plugin conditions not being applied to mobile browsers


I am using the Pop Up! plugin on my website. It works great on desktop browsers, but I see that conditions are not being applied in mobile browsers.

For example, I have a condition to show the popover only if it has been seen less than 1 time. I also checked the 'Regular close button acts as "Never see this message again" link' box.

However, on both my iPhone and iPad, I continue to see the popover each time I reload the page or visit a different page on the site.

Please advise.

Thank you,
