This issue was mentioned here a year ago, and for whatever reason there seemed to be a communication breakdown and the point did not get across.

Collection Instances are treated like objects rather than collections so none of the collection-level custom properties carry over. I understand why collection instances are treated like objects, however whatever the appropriate handling ought to be, I think dropping properties into the ether is not it.

"Collection instance" is an "Object" , not a "Collection", so the properties from the instanced collection won't show in the instancer.

To make life easier for your purpose, you could try registering a panel yourself which "adjusts the properties of instanced collection from the instance object".

Closing this for now since it's not actually a bug with blender, but feel free to comment

If a Collection can become an Object then why can't a Custom Property belonging to a Collection become a Custom Property belonging to an Object? If the new Object (Collection Instance) encompasses everything about that Collection (to include all of it's geometry) why would it not also encompass it's custom properties? All I'm hearing is that this isn't the case because it isn't the case without any further justification
