I just got the Samsung S23 Ultra and I set my default text messaging app to Message +. I set up all notifications to be a specific sound within the Message+ app. (Message+ Settings - Customize - Notifications - Sound). However it only wants to use the notification sound within the sound settings of the phone itself. I don't see any other thread that fixes this issue. I need help trying to get Message + to use the correct notification sound for new messages without having to change the notification sound for all notification for every app on the phone.
