Thank you for the detailed assistance! I apologize for opening the topic when I was in the middle of a meeting and couldn’t follow through with the instructions. I can attend to it now.
I’m not seeing any “Advanced” section. But I found it.
Notification Settings → (list of notifications by category, with 3 toggles under each)
Messages (touch the word to the left of the toggle) → Sound
I completely missed that the words to the left of the “Messages” and “Miscellaneous” toggles each opens another menu. There’s no distinction from the Show Notifications toggle above them.
(I’m running Android 11 on a Samsung, there may be a few UI differences from stock.)
If my description is confusing, maybe I should create a Demo account and grab a few screenshots.
EDIT: I understand now that’s what you’re trying to show with the red arrow. It’s a menu button that’s not decorated as a button.
EDIT 2: That’s the meaning of the tiny vertical bar to the left of the toggle! So there IS a visual affordance that I completely didn’t see.
Thanks again for the help.
