Contacts not recognized

I have my nextcloud contacts setup with DAVx⁵. It’s syncing correctly and shows up as expected in the contacts app.
However, in the Messages app and WhatsApp, I only see the phone numbers listed, even though the contacts are listed when I compose a new message.

Any idea how I can fix this?
Thanks!

First: That’s sounds very bad. Never install the most spying app in normal profile. If you really, really need Whatsapp, put it in shelter [HOWTO] Using WhatsApp under shelter

No you problem: Do the apps have access in your device settings/apps/ access to contacts ?

Hello and welcome.

In your Contacts list, only your WA contacts are shown “normally” with name, aren’t they ? So you’ve got the answer, I think…

Ah that was it, thanks! And thanks for the link, will check it out.
