This may well have been mentioned in the nearly 1000 previous posts, but the displaying of CPU status seems to vary wildly. I have a record that sometimes shows the blue CPU symbol
Sometimes I login and see nothing about CPU, almost like I have been removed from the CPU list like I do when I travel with my family in E.
Other times I see the upgraded segments as waitlisted.
