The new card tracker can only track 5/24 if we are able to enter cards that you do not support from a benefit tracking POV. So, I have (or have had) an Apple card that is within the 5/24 window that I cannot add. I also had some co-branded cards in the 5/24 window but cannot add them.
One other note: The OG Chase Freedom should be on the list since people can product change to it within the 5/24 period. I did that, but instead of entering it, I just entered the CSR and marked it as closed.
