WhatsApp missing from Setting--> Notification list
I recently bought an Apple Iphone 13 Pro and copied the data from my previous XR. Everything worked fine, but for some reason, the notification list under settings does not contain WhatsApp. It appears all other apps are in the list. Can someone advise how to get this added to the list so I get notifications again? I am afraid to delete the app and reload, as I think I will then lose all history.
Any ideas? Many thanks.
iPhone 13 Pro, iOS 15
