I checked out of a Courtyard on Feb 14th and the charge ($567) hit my Amex Bonvoy Brilliant card with that date. My anniversary started somewhere around September and I have not used any of the $300 credit yet (in fact, this was the first time I used my card since mid-2019).

I had also enrolled in an Amex Offer ($50 worth) for Marriott spending and I see that the credit for that ($50) appeared on my card on Feb 16th. However, there is no sign of the $300 credit (I got the 6X Bonvoy points for the $567 spend so it does appear as a Marriott charge). Last year's (2018 Sep-2019 Sep) credit had appeared only two days after the qualifying charge so I'm a bit confused and worried about why it's taking longer than usual. Are there any recent data points about how long the $300 credit's taking to appear?

Thanks.
