Peacock Premium Perk Broken

I'm a Platinum Xfinity Rewards member and received the email to claim my included Peacock Premium perk on 7/23. I've followed every step in the process, first attempt on 7/24 and again on 7/26 and hit a dead end at each stage:

1. Clicked "Redeem Peacock" from the email → taken to the membership page, which confirms: "Nice! You've redeemed this benefit."
2. Clicked through to activate at xfinity.com/yoursubscriptions (StreamStore) → banner says "You don't have any Xfinity subscriptions yet" and pushes me to purchase streaming bundles, rather than showing my already-redeemed Peacock benefit. After clicking "Manage streaming apps" I am taken to https://www.xfinity.com/digital/entertainment-management/internet, where there is a banner saying "You have subscriptions that require activation. Activate now." Clicking this link takes me back to xfinity.com/yoursubscriptions.
3. Tried peacocktv.com/partnerlaunch directly, entering my Xfinity email → get the message: "Sorry, we can't activate your subscription. We're sorry, something went wrong on our side. Please try to activate again."
4. Tried signing into peacocktv.com directly with my Xfinity email/password → not recognized.
5. Tried peacocktv.com with my existing separate Peacock account password → logs in fine, but that account shows no subscription.

Could someone from the support team look into my account directly and advise on how to proceed? Happy to provide account details via direct message as needed. Thank you.
