We would like to remove/hide the ID … Version … reference in the upper left corner when an objects metadata is presented.
Is this possible?
Yes, this is possible. If you have access to the metadata card configuration, you can make a static/constant rule that applies to all objects.
Create a new rule with no filter settings:
Under Behaviour > Metadata Card > Theme > (Object Id Field & Object Version Field) set Is Hidden to Yes.
This should be applied instantly.
Let me know if this works.
