Flex box needed for Peacock Premium reward?

I dont know if its needed to activate the free peacock perk but I did use it to activate mine. Also flex is basically xfinity version of say a roku box. 

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

Hello, thanks for reaching out. Please use this link to subscribe https://www.xfinity.com/xfinityassistant/. Once there you will want to click on the "Activate Now" on banner that states "Your Peacock subscription is ready for activation"

You will then enter the email address and password you want associated with the Peacock account. This can be the same as your Xfinity account, but it does not have to be. If you have a previous Peacock account and want to retain the preferences/history, you should use the same email address you normally use to log in.

Xfinity Rewards Diamond and Platinum members with Xfinity Internet can redeem a special offer for Peacock Premium at no additional cost from the Xfinity Rewards website. You must be enrolled in Xfinity Rewards to take advantage of the offer. Once the offer is redeemed, you’ll continue to have access to Peacock Premium as long as you remain enrolled in Xfinity Rewards as a Diamond or Platinum member with Xfinity Internet.

Are you now able to subscribe?

Thanks much.   After multiple calls over several weeks the “activate now” option finally has shown up.   Even though I cancelled Peacock it is still active for a few more weeks.  I’m being given a notice the “activate now” function can not activate until my Peacock subscription ends in a week or two.
