It's actually a bit confusing, you're right :P
What happened was that on versions of Android where notification categories weren't present, there was the notification
Priority. This used to be the main thing that controlled how the notification behaved.
With the introduction of
Notification Categories Google deprecated
Priority and now each category has its own
Importance which is similar to the priority but a bit different in some ways.
I reused Tasker's existing setting and now "translate" the old priority to the new importance. I do the same in AutoNotification actually :)
They translate as follows:
Notification.PRIORITY_MAX, Notification.PRIORITY_HIGH -> NotificationManager.IMPORTANCE_HIGH
Notification.PRIORITY_LOW -> NotificationManager.IMPORTANCE_LOW
Notification.PRIORITY_MIN -> NotificationManager.IMPORTANCE_MIN
else -> NotificationManager.IMPORTANCE_DEFAULT
This is all super technical and I don't think users will generally care about all these details but I'll add a part about the priority in the help. Thanks for the feedback! :)
