Not receiving notification sounds when screen is off

[Figureguy]

I have a Galaxy A13 5G.  Up until a little while ago when the screen is off I do not receive notification sounds.  I honestly do not know if it happens when locked or just timed out.   I also do not receive notification bubbles of any sort.  The screen stays off until I hit the power button and then all of a sudden whether it needs unlocking or not the sounds and messages appear.  The notification icons are there but it is if someone just turned the volume on.  If the screen is on and I am using the phone the notifications for say, X, come across perfect and make sound.  I have been checking individual app as well as system settings, looked online and watched a few Youtube videos.  It used to work fine for me.  Thanks in advance.

Hello 👋 @Figureguy 

I have seen some recent posts about instances similar to yours. 

May I suggest to perform a forum search as you may find already existing threads with help and advice within.

It'll be power saving mode settings or permissions

Thank you for responding.  I did do a forum search as well as Samsung forums from other regions as well.  There were some solutions indeed offered but none of the ones available worked for me.

Thank you for responding.  All permissions for notifications, not only through the Twitter App but the phone in Notifications within settings are all set to make sound at all times.  I do not use power saving mode and nothing that restricts battery usage.

Still having the issue if anyone can help.  I talked to Samsung and we reset the settings on the phone but nothing changed.
