I just spoke with AMEX. Two agents informed me the offer ended 8/31 and has not been extended as of yet. They offered me 30K points or $100 statement credit if I charge $1,250 in 3 months (I charge way more than that)
I did not accept the offer - I have 30 days to cancel and not pay so I will see if the food credits keep posting (a postmates $9.99 credit did post in September, but an Uber Eats the same day did not).
I may just downgrade the card
