Notifications from some apps are missing

It is possible that BuzzKill doesn’t have access to some categories of notifications or notifications from specific apps.

Try going into system settings, into notification settings, into “notification read, reply and control” and then into BuzzKill. Then make sure all the categories are ticked and when you tap “see all apps” that that app that is missing is ticked too. From that point on, see if new notifications start appearing in the history tab and also triggering your rules.
