I can't remember exactly what they said about the system downgrading them but I do remember that when we both arrived at a hotel together around the 8th January the front desk said they were gold rather than plat so it does happen fairly quickly as most stays will have posted by around the 5th.
Not sure if that helps you, apologies if it doesn't.
