You can now block worst-performing mobile browsers, allowing you to further optimize your mobile Zeropark campaigns. To do this simply set up a mobile-only campaign by selecting the mobile-only option on the campaign set up page.

Once the campaign is set up you will see a new tab on the campaign dashboard labeled Browsers. When you start buying traffic this tab will populate itself with the browsers you are buying from allowing you to pause them as you would a target or a source.
