Peacock App Does Not Load on Xfinity Flex

[Shlok]

I just got my FlexBox today and the Peacock app does not seem to be working. I can see the App Logo but the screen does not move past it. 

STB Version - AX061AEI_4.0p19s1_PROD_sdy

I am hoping someone can help me out! All other apps seem to be working fine!

Thanks!

EDIT: 

Switched the FlexBox on and off twice, and the peacock app seems to work now. Not sure if this is a definite solution, but as per the Comcast representatives, turning the FlexBox on and off upgrades the Firmware (if connected to the internet) to 4.2 which is required for Peacock App to run/load.
