For several years, I've had both an Am-X Plat and a Marriott Card which both conveyed Gold or Gold Elite status at Marriott Bonvoy. This year, Am-X somehow unenrolled me and now they have re-enrolled me but (after a month) Marriott is still saying they don't see the account being linked. In previous years, I would see them both on the Marriott account and it would add up to 50 promotional/bonus nights under the "nights this year" section of the my account.
