I can only repeat and confirm the problem doesn't happen, and it's exactly as it always was.
If you park too short, so the marshaller hasn't even started the "cut engine" animation, it will wait for you to proceed forever. Nothing has changed since GSX has been released, it has always been like this, you must be inside a certain distance threshold of the Stop position for the "cut engine" animation and message to be triggered and THEN, the marshaller will give the evaluation and will go away.
Right now, since GSX has been released, the threshold distance it's 50 cm ( 1.64 ft ), so you are shorter than that and stop there, GSX is still waiting. We might increase this a bit, to make it easier, but it's a value that has been there since forever.
