Hello,
What is the best way to access the subject expression using python arcpy.mp module (if possible?)?
Thank you,
Tyler
Did you see the code example in the CIM ?

This might be a helpful page? Python CIM access—ArcGIS Pro | Documentation
Thanks @AlfredBaldenweck. I ended up there and was able to access the unique value symbology expression and make it work.
Cheers,
Tyler
