I have my board configured so that Guests can't view any of the Activity Streams. However, I don't seem to be able to hide the Status Updates stream. It still shows and loads the contents to guests.

I can't seem to track down where the permissions for the status updates might be hiding. Any help would be very much appreciated.

I would need more information on this. How is it you have removed permissions? If you havent already, you should really remove permission at a module level from the content discovery module

Perfect, thank you. That's what I was looking for.

No problem at all 🙂
