NativeX staff has tools to set limits on the # of single offer reward, or non-reward, ads shown to users in your app per period of time (minutes, hours, days). For example, we can limit the number of interstitial ads shown to your users to 5 ad impressions per 4.5 hours. These settings are not currently available from our web-site. Our team is available to customize your user limits for showing ads for apps with greater than 10,000 daily active users. Contact NativeX if your app qualifies and you are in need of added support.
