I did 1 night at Delano and 4 nights at Bellagio booked through Hyatt app and they didn't post yet 2 weeks later. Asked my concerige and he said up to 30 days so hopefully they do credit before New Years as I did these 5 stays to keep my Globalist 60.

Anyway now I got the MGM Gold match actually working whilst I was there, but they didn't comp the existing resort fees which I guess was fair. But I am planning to go again next week and will now book through the MGM app so I can get the resorts fee waived and then I believe my Hyatt nights will still post and credit from there.
