A week later, still no email or official notification but the website started working for me. That said, it's pretty clear the data is busted. Somehow Guangzhou is my #4 most visited city despite only visiting once for 2 weeks (albeit going on a small hotel crawl and seeing some lovely properties) while Taipei (a place I have visited for months in aggregate) doesn't even make the list. My guess is they are including Shenzhen, Hong Kong, maybe even Beijing under "Guangzhou"... it's the only way the listing makes sense.
Also they couldn't render the name of their own brand correctly? You heard it here first, Le Macridien will be the 35th Bonvoy brand 😂
