AAA has recently developed a new AAA Digital Membership Card for your Wallet app. Previously the AAA Mobile app installed a card into your Wallet - this was a White card with Blue type. This card is no longer supported and should be replaced with the new card. This new card has a Blue background with White type.
To remove the older White card, open your Wallet app, scroll until you see the white AAA card with the red and blue logo in the upper left corner and the words Membership Card in the upper right. Tap on that card, tap on the circle with the three dots in the top left of the screen, tap on Remove Pass, then tap Remove.
