Issues with Processes starting based on multi select field updates

Issue/Introduction

We have one process which runs on update of a multi-select field.

Process has following start condition:

( Idea Co-Authors != Idea Co-Authors [Previous Value] )

The process is started every time any field is updated on the page (even though Field Idea Co-Authors is not updated)

Expected behavior is process should not start, if Idea Co-Authors field is not updated.

Resolution

it is not possible to create start condition using expression builder with multi valued lookup to be able to compare to the previous value.
