Hello @Anil_Babu_Samineni , @Hanne 

I've found the cause of the issue.

On January 30th, there was a release of 2 new user roles to access AutoML.

The Auto assign setting for these user roles is automatically set to 'Anyone within the company' in stead of 'Off'. All of our basic users got this role automatically and thus were transferred to a full user license, which is definitely a bug, and not what you need at that point.
