This is how I fixed my wife’s notifications after IOS update. Basically all you need to do is deactivate the Bluetooth and reactivate it between you phone and watch which will prompt your phone to alert you to authorise smart notifications!
when you click on Bluetooth and ️ the tab share system notifications should be green
If this helps 1 other person my job is done!
