Contacts being there but not showing up.
This is a problem I have for about a year, since I upgraded to the iPhone X, and had all the way through all the iOS updates. All the contacts I enter don't show up on my contact list, or my whatsapp, but if I retype the number or they call me, they do.
So far the only workaround I've found for this is to immediately call them after entering. That makes them appear. The ones entered before I started using that method, still don't show up even if I call them, so I have to delete them, and readd them. You can see how that can be a problem.
I'm sure the solution is really simple, but haven't worked it out yet. I have searched and tried unsyncing it with iCloud, tried checking if the contacts weren't on a different unchecked group and restoring the phone.
Any help would be appreciated.
Thanks in advance!
iPhone X, iOS 12.1
