-Open your Do Not Disturb setting. -You "should" have a section labeled: Exceptions at the bottom. -One of the categories in there should be "Apps" -Click Apps -In the upper right corner (at least on the Note10+) there's a plus sign where you can add any app to your DND Exceptions list. -Just scroll through your list (if your adding a System App, remember to toggle that search on) and select the App your looking for. -Once you've found and selected your App, you can then set the specific parameters you want that App to bypass for your DND so you'll get your alert. -Ex: I added the Message+ App. Then I added to only bypass DND if a text message came through from a contact that I have marked on my Favorites List. I did the same thing with phone calls. Hope this helps.
