I want to ensure API Only logins cannot access our Chatter feeds by using the Salesforce Chatter for Mobile app. I created a dummy API Only user and deselected everything on the Profile, but I can still log in as them via Chatter for Mobile and see and join Chatter Groups. This is a security breach for us so I'd be extremely grateful if someone knows how to restrict a login from accessing Chatter in any way. Thanks all.
