I had no idea you could do this. But I just found out that when long pressing on a folder where badge is showing you can see a preview of which apps are flagging a badge. Kind of useful if you have multiple apps in a single bundle and don’t want to scroll through them all to find which is sending a notification. Probably useless or known for most but I have seen much more useless tips on YouTube 😅

Thanks, OP!
