So I have a decent amount of apps >100 on my Samsung A8 and would like to reset all of their notification channels to urgent/popup with sound. I didn't understand when I set all of the setting initially what I was doing and realize now that I have messed up. I have done "reset app settings" in the app menu of settings, "reset all settings" & "Factory Reset". Notification settings are persistent for some reason. Is there an app that can let me control them in batch?
