I am working on how to restrict some group of users from creating a connection on the hub. I restricted them to have access to QVD folders only however, data connectors still appears. Please, how do I disable "Connect my data" tab on the hub?
Had the same issue using June 2017 edition. What you mention here is KEY! Whenever you edit/disable the existing "Data Connections" security rule, the change applies only for new apps! Does not apply for the existing apps.
This is funny - and in my humble opinion, it is also a bug.
