Edge lighting not working

I have not been able to get edge lighting to work on my 25 Ultra. I've done everything except a factory reset. Any suggestions. All app have been updated. Using Google Messages

Do you have your notification style set to Brief or Details in the Notification settings?

I've only found Edge lighting to work when "Show as pop-up" is enabled in the app's notification settings. It's the same page with the Alert/Silent, Sound, Vibrate etc. toggles.
