Are you using the app?
I don't think that it's worked via the app for a long time.
Try the website instead.
I think it works there.
It did the last time I tried it.
Except sharing with contacts which needs the app.
But doesn't work anyway as far as I know.
If it does work then your contact also needs to have the app installed and granted permissions to access their contacts.
If you need to contact 48 support about this then see the links in my signature below.
