Were you by chance within 30 days of your Boundless AF posting when you upgraded? (Or whatever the amount of days it is for Chase that they refund the AF if you cancel a card which I know for Amex is 30 days?)

Then I'm wondering if your next AF for the Ritz will be charged on the original anniversary or a year after that first Ritz AF was charged?

We're upgrading now from the Boundless to Ritz a few days shy of second anniversary so hope to have my own DPs to share but it's not completely clear to me on how the AF for the upgraded Ritz works as it seems people have different experiences.
