Not true in my experience. Consistently receiving rewards at Simon for both P1 & P2 since the first week of their 3% card launch. Heavy hitters just want people to think this stuff so people stay away in hopes it will keep it alive longer. It's the same as the people trying to claim certain gebits don't work for paying CitiBank over the phone when they still do. When in doubt, test it yourself so you'll know the truth.
