Banner & MREC ads

Banner and MREC ads are rectangular ad formats that occupy part of an app’s layout—often at the top or bottom of the screen or inline in scrollable content. They remain visible as users interact with the app, which allows uninterrupted gameplay or use, and can refresh automatically after a set period.

The following sections show you how to load, show, and hide a banner or MREC ad.
