Where did the auto assign (Round Robin) feature go in Ver. 14?

Where did the auto assign (Round Robin) feature go in Ver. 14?

We recently upgraded from Ver 11 to Ver 14.2 and had been using the round robin auto assignment feature but it is no longer available.  We are on a Professional level license.  Is this another feature that Manage Engine has moved to the more expensive Enterprise level license? I have tried to find any documentation on this but only find very old topics(over 5 years ago) and it is not specified in the release notes nor the feature comparison.  Has anyone else lost this feature?
