Chase has been testing a new Offers interface for the last few weeks, which has a fun bug that prevents the new layout from updating after adding offers via the CardPointers extension (and in some instances in their own interface directly).
As long as you see your offers in the CardPointers or Chase app, those offers have been added to your cards, and the new Chase offers interface will show that within a few hours, it just takes some time to catch up.
Hopefully Chase fixes this on their soon as it’s definitely a bit confusing, but as long as your offers are showing in the app they have definitely been added and the offer will be redeemed when you use the card to which each offer was added.
