@Tyler, there is never a one way fits everyone. I guarantee if you remove the $0 balance notification all together you will have other units that will come to the Community asking why it went away. Most people only come here when they have a problem, they are not necessarily staying up on current discussions. I think overall the best course of action would be to leave it as is until the dev team can come up with a way to give choice to each unit through settings for how to handle Money Account Notifications. I do remember discussion previously from units that wanted the $0 notification because they do not allow Money accounts to go negative.
Your information about how an individual can turn off the notifications for themselves is invaluable as it does not require a system wide change and only those that don’t like the notification can choose to turn it off for themselves.
