my escalibur stay 11/20-24 has not yet posted yet either. I’m hoping it has something to do with the holiday. I reached out via twitter to Hyatt and they told me to wait until 14 days to request missing credit for MGM stays. On Thursday I will email MHC to ask them to submit a missing stay request. As a data point I used digital check in which previous poster has said is less likely to get credit.
