No sound notification of incoming SMS messages


Feb 5, 2021
Hello, this problem appeared today all of a sudden. When I receive an SMS message the notification bar does pop up on the screen but there's no sound to it (as it used to be until today). Also the notification diode doesn't indicate that I've got a new message. I've tried rebooting my phone, emptying cache and it did nothing. My system sounds volume is all up. I'm using Google Messages app and my phone is MI A2 Lite, Android 9.
Thanks in advance.
