Moderated Channel - mobile users can still "meet now"

Hi there, 

I have found in our org-wide channel that even though I set the "general" channel so only Owners can post, I have found that in the mobile app, users can tap "meet now" - meanwhile on the web and PC app they cannot.

The latter (NO meet now icon) is the expected behaviour, so I think it's a bug w/ the mobile version.
