Too much nagging! Hey Viber I'm already yours no need for self promotion! Why one cannot quit receiving Viber's constant self promotion messages other way than denying notifications permission from the whole app and denying autostart. Though, it doesn't help, because now viber keeps nagging with the warning of the turned of notifications every time I open the app. As a consequence I started to redirect my friends to another way to communicate and use Viber less and less.
