One thing I noticed when I was configuring the various apps' push notifications in the Note 12 Turbo. Thought I would share about it.
Besides toggling the usual "Autostart", "No restrictions" for the battery usage and "Yes" to notifications for each of my essential apps, I still had to tap on the app's Notifications again to dive into each different notification category to toggle further.
I noticed that even after I had enabled "Yes" for notifications, the individual notification categories under the app were mostly off by default for Floating, Sound, Vibration, etc. So I had to manually customize each and every single thing before the notifications were functioning properly as intended.
