We’ve written about the problems that the new Amex credit card interface has. The biggest issue is that on the new interface an offer saved on multiple cards in the login disappears after being used on one card. This is not because it won’t work on the other cards. It’s just a function of the new interface.
Use the old Amex interface, especially when checking your Amex Offers. A lot of people might like other things about the old interface better as well. Actually, the new interface got a bit better since I last wrote on the topic, but the old one is still better overall, in my opinion. Another option is to use the mobile app.
Note, the new interface works fine to SAVE the offers. It’s only when referencing the offers after they were saved that you’ll want to be using the old interface specifically.
I’d thought most people were aware of this already, but time and again we’re bumping into comments, Tweets, and forum messages by people stumped with what’s going on with their Amex Offers, so it’s was worth a reminder.
