So for the longest time, I have always received Marriot Bonvoy points.  Two weeks ago, I had booked a room at a Delta and for the first time this did not show up in my Bonvoy app.  Called the hotel to have it added, no issues.  Now Marriot is telling me it was booked through a third party website and not eligible for points.  I will add I have stayed at this hotel many times booked through Concur with no issues.  

Was there a change to how Concur communicates with Marriot that might have caused this difference in treatment?  Will note I have 2 other upcoming reservations which flowed through with no issues.
