Issue description: On my private page only, notifications (observed for "follow" and "post liked") never produce a notification badge, but do appear in the notifications page for that account. This led me to believe that no one was engaging with any post on my private page, despite several posts being liked.
All notification options are checked. Follow requests still produce a notification alert badge, but nothing that appears in the main notifications feed.
Expected behavior: like other types of page, a post being liked / commented on / etc produces a notification alert for that page if the appropriate setting is checked.
