Macbook Pro Retina 13" not showing up in iCloud under "My Devices"

Hi there

I just installed iOS 8.1 on my iPhone 5 and Yosemite on my macs (I have 2 MacBook Pros, one is Winter 2009, other one is early 2013). Everything seems to working fine and I can see all my devices under "Find my iPhone" on iCloud.com.

But I noticed a strange behaviour. My newer MacBook Pro 13" Retina is not showing up under "My Devices" tab in iCloud Settings on iCloud.com where it says "You are signed in and running iOs 8 or OS X Yosemite on these devices". I am logged into my Apple ID in iCloud in System Preference. Moreover, my iCloud Drive is working fine too.

Please assist.

Thank You.
