No notifications on locked screen after updating to 14.4 iOS on iphone Xs

I just updated my phone to iOS 14.4 and my phone no longer vibrates or even lights up when notification is received on a locked phone. That is the case whether the phone is on silent or not.

Is this a know bug?

If the solution is to reset the phone i am not really willing to do that, as it was working perfectly fine until i have updated to latest iOS.

I have also checked the obvious settings, notifications, silent mode, night mode etc etc etc

i also have an apple watch, which i just updated. Is it a new feature that when notification come on the watch they dont appear on the phone? If thats the case its an awful feature !
