SELECT id, view_href, subject, videos, videos.count(*) FROM messages WHERE videos.count(*) > 0

Hi shayl Could you give me an example of how you're making the request? In an endpoint or component? via the rest or restadmin context object? Or some other method. Also, how are you using custom tags in your Community? (A brief overview of the kind of metadata you're adding to messages, for example.) 

Update: One of our Services team members just reminded me that there are permissions around seeing custom tags. You might try reviewing this set of permissions in Admin.
