Looks like Chase finally fixed how they post the Edit credit
I booked an NH Hotel on Jan 4 Sunday after 5 pm. My credit card transaction is showing as pending as of today Jan 6 Tuesday, but my travel statement credits meter are showing I only have $250 Edit Stays credit as of Jan 6 and $0 for select hotels credit as of Jan 6.
But, I don't know if the reverse (i.e. if you cancelled the booking) will be the same.
