Similar frustration and mind boggling for me when I found that the "custom focus" feature on iOS just does... nothing. It's a feature where you're supposed to be able to select which specific apps can send notifications to you, so I made one which allows Slack to come through (for work) and blocks everything else. Instead, it just allows everything through as if the "custom focus" wasn't enabled at all. No seriously, I'm baffled. How was this released?
