Note: Ensure that critical sections of your app, for example buttons or text, do not sit within the left margin of the screen when displaying a Thumbnail ad.

MFThumbnailAd *thumbnailAd;

- (void)createThumbnailAd {
    // UI on main thread
    dispatch_async(dispatch_get_main_queue(), ^ {
        thumbnailAd = [[MFThumbnailAd alloc] initWithPlacementId:@"000000"];

        [thumbnailAd registerAdCallbackReceiver:self];
        
        [thumbnailAd loadAd];
    });
}

Note: Ensure that the SDK has fully initialized before creating your ad units. You can use the onInitSuccess callback as a good place to set up your ad units.
