I run CC on two machines. One machine updates normally, and when it does I know that the other machine should as well, but doesn't. I've contacted Adobe in the past to resolve timely issues, past updates were solved, but the problem of not showing updates when they are released continues.
At present, I did not get the ACR update for CC, CC 2014, CS6, Bridge, Lightroom < I think that the other machine showed that these were all updated, but I might be mistaken (actually I do remember that 4 updates were called for).
I'd do another Chat w/ Adobe, but I wonder if there is anyone else out there that has a better understanding why my connection to CC desktop seems busted.
