In the past week or two, the web site worked fine for a while and then returned a blank page. Restarting my browser solved the problem at least once. Yesterday, when I wasn't in a hurry, I decided to see if the problem would time out and left the tab open. Today, refreshing the tab still returned a blank page; closing the tab and revisiting hyatt.com in a fresh tab resulted in a blank page. I'm using Firefox 133.0 (aarch64) on a MacBook Air M1running macOS Big Sur 11.7.10, but it really feels like a Hyatt issue. (Off-topic, does anyone know what "aarch64" following the Firefox version number means?)
