Folks who have had their status reinstated back to Platinum, is there something specific to be done?
I would think best to let this "refresh" take its time in the database, but I'm not sure if there will be another round of updates after this one to correct the ones who do miss out.
FWIW, I've had the card for over 4 years and did spend over $10k before the 2018 cutoff date and was Platinum up until a few days ago... have over 15 nights already booked for 2019, so this being broken will be a big headache.
