Marriott bookings via Amex Travel don’t earn Bonvoy points

Quick question, I’ve booked two stays at two different Marriott properties and in both cases the stay did not register in the bonvoy app nor were loyalty points awarded. At first it seemed like a glitch with the first hotel. Upon check in I asked why my stay wasn’t showing up in the bonvoy app and they said that my loyalty info wasn’t attached to the reservation. They updated it and claimed it would be fixed in 24 hours. That seemed weird but I said ok. Long story short; it didn’t fix either issue. I called Marriott CS and they are now claiming that Amex/Expedia rates don’t qualify for Bonvoy awards.

Is this a new change in the Amex relationship with Marriott?
