Reader S2M-824E pointed out that some cards are now showing more than 100 AMEX Offers. At the moment, this seems to be happening on the AMEX Platinum family of cards. AMEX Offers now include many credit card benefits, and Platinum cards themselves come with more perks, so that may be part of the reason. But in the past, no matter how many there were, the display would max out at 100 addable offers. On several of my other credit cards, the maximum still only shows as 100. Reader S2M-824E is seeing more than 100 offers on all of their cards, so it probably does not have much to do with the specific card type.
