Submitted proof of status with Hilton on Marriott's status match webpage. A few days later I had an email stating I was approved and had 90 days to stay 15 night in order to keep Platinum Elite or 10 nights for Gold Elite for 1 year. However, I caught their status match right before it ended. The status match FAQs page now states:
"Registration is Now Closed. Due to a Large Volume of Applicants, registration for this Marriott Bonvoy™ Elite Status Promotion is now closed. All of us at Marriott Bonvoy™ look forward to welcoming you soon."
