I received a replacement Sears ThankYou Mastercard in the mail, but can't see what changed.

My current card expires in 2026 (2 years from now), so this is quite early for a replacement card due to expiration date (the new card has 2029 expiration date).

I did not request a replacement card, and have not been having any problems using the card that I have (tap-to-pay and chip both work fine).

I am trying to figure out why a replacement card was sent out when nothing seemingly changed. Anyone have a similar experience?
