OOTB and Custom UI Policy Not Working In Service Operations Workspace

I’m encountering an issue with the OOTB UI policy "When state is On Hold, the On Hold reason field is visible and mandatory" in Service Operations Workspace.

After setting the state to "On Hold," the "On Hold reason" field only becomes visible and mandatory after the record is saved.

This also happens with UI policies I’ve created, where the UI Policy Actions only take effect after the record is saved, making the required fields mandatory — which isn't the expected behavior.

It works as expected when I tested it on my PDI

Has anyone else faced this issue in Service Operations Workspace, and how did you resolve it? It works as expected on the platform side
