Adsense App will discontinue for Android and iOS
As Google said previously that they will discontinue the App services for iOS and Android, and they will better support Adsense for Web interface. Now it is seen that Google is notifying users that "Adsense will stop supporting this app in the next few months".
Google wants you to use web interface only to get detailed information about views, clicks and all. Google thinks it's better to use web version instead of App for better analysis about Ads.
