I use to use this and worked fine then I found out that another plugin conflicted with it. After removing the other plugin I can only see the ads popup on my site using my Android App. I can't see it in any web browser that I currently have I have disabled adblocker plus. This issue also occurred with SlideIn, and I've never used it again. I'm currently using another popup ad, and it seems to work on all browsers and my app. I've deactivated the other ad pop so that you can go to my site and see the PopUp Pro ads. I hope they work for your tech support. Also my site goes to white when Popup Pro is Active.
