Requesting Help with Activating Peacock Premium Perk for Platinum Member

Hello. I received an email recently from xfinity saying I qualify for a free subscription to Peacock Premium, a perk that I can claim as a Platinum member. I followed the link to redeem the perk, but my account showed that the perk had been redeemed already. When I click the link presented to activate, it says "Visit StreamStore to activate Peacock Premium," but Peacock is not listed anywhere on the new page of my Streaming Subscriptions. I also don't currently have a Peacock subscription I am paying for.

I have read through other chats on the forum reporting the same activation issue, and have tried all the remedies proposed (logging out of xfinity and Peacock, clearing the cache, trying incognito, going directly to the Entertainment Management page, etc). It seems the only resolution that has worked for others is filing a ticket for an agent to manually reset the rewards entitlement on the user's account. So I am kindly reaching out to get direct technical assistance with rectifying this issue on my account. Thank you very much in advance for any help you can provide.
