Peacock and moving - has Xfinity figured it out yet?

I've seen posts going back a couple of years on this, but no real resolution. We subscribed to Peacock Premium as a gigabit customer and then Peacock Premium Plus to get ad-free. We just moved to another state and another gigabit plan and somehow our premium plus disappeared. When I try to activate Peacock, I get the notorious error that it's already activated with another account. We only use one account and one email address.

How do I get this fixed?
