Sure - sorry I don’t know the answer!
Hello, enoch -
I have a Samsung Galaxy S21 (and four Galaxies before it) and know from my own use and helping friends that its settings go deep. Usually the default is that it makes a notification and you have to dig into it to prevent the notification, but your case may be the opposite.
If you want me to look at your phone with you, we can do a Google Duo video call and you can share your phone screen. Maybe together we can find the setting that will allow the notification. Reply or PM me (and hope I see that notification!) if you want to try that.
I agree with Dane that the problem is not at Sonic's end.
