this is weird..Just received this email (did the status match again last week)
We’ve got good news and bad news: Unfortunately, you did not stay enough qualifying nights to keep your DIAMOND level match. However, you’re still a DIAMOND member and can continue earning and redeeming points toward free nights at more than 8,000 Wyndham Rewards Hotels worldwide.*
Plus, as a DIAMOND member, you’ll enjoy exclusive perks** like early check‑in, car rental upgrades, and more.
It also says I must stay 14 night by 1/14/19 .. maybe it expired and now the new match kicked in..odd
