I'm having trouble editing a whatsapp contacts' name. I feel like I've tried EVERYTHING you can possibly try by googling; deleting the contact, playing around with whatsapp permissions, etc.
Also: if I'm on the contact page in whatsapp, clicking the dropdown-menu "edit" or "view in addressbook" simply doesn't work, so I think this is some kind of sync problem. I have this contact saved in my contacts list with the desired name, whatsapp just doesn't want to use that name apparently. I can even see the whatsapp "voice call", etc. options from the contacts screen in my contacts app.
In my contacts app (Nexus 5X, btw), when I select "All Contacts", there's only one version of this specific contact, under the correct name, so I don't think there's a duplicate with the wrong name, unless whatsapp has somehow hidden this duplicate.
Any insight is very appreciated, this is extremely infuriating!
(How it seems to me: Whatsapp has some kind of hidden contact list somewhere that I can't view/edit, from which it keeps syncing the wrong contact name)
