Pro 4XL Notification tone has vanished

[Puddleglum2]

My Pro 4XL used to notify me if motion was detected by both a pop-up notification and by a chime (default o/s sound). Now the sound has disappeared.  How to I get it back?

Thanks.

This is my question also. I see no other response

Check the phone's settings for the app. Click on Notifications and then Notifications again (NOT the slider) and set up the notification sound.
