On Windows 10, in Settings > Notifications & Actions I have notifications turned on for Slack. If I click on Slack it takes me to more notification settings for Slack. On that screen I have Show notification banners set to On and Show notifications in action center set to Off.
I do see the toast-style banners pop up when I get a Slack message. But I also see those same notifications in the action center, which makes me wonder if I'm misunderstanding the setting.
Is there a way to have the toast banners and not have the notifications collect like so much sediment in the action center?
