        ContactBatch batch = null;

        // *** This RequestStoreAsync() call is where the exception is thrown. All the cases below have the same issue. ***
        //store = await ContactManager.RequestStoreAsync(ContactStoreAccessType.AllContactsReadWrite);
        //store = await ContactManager.RequestStoreAsync(ContactStoreAccessType.AppContactsReadWrite);
        store = await ContactManager.RequestStoreAsync();

        list = await store.FindContactListsAsync();
        foreach (ContactList contactList in list)
        { …
