Owncloud 10 - Share contacts is not saved

Steps to reproduce

  1. I have 6 users in one usergroup. I use contacts app. I created with one user one contact in the standard addressbook and try to share the standard addressbook with the usergroup. I use another bowser to log in with a second user in order to see the shared addressbook/ contact.
    If I relaod the contacts using the first user the share is gone.

Expected behaviour

I can choose the shared (standard) addressbook with any of the 6 users in oder to see and edit the contacts in this adressbook with every user.

Actual behaviour

There ist no shared addressbook. The share of the addressbook of the creating user is not saved.

Hi Tom 42,
