Currently, on iOS, when a device has "Larger Accessibility Sizes" enabled, the app loses many components.

Most critically, the "Checkout" shortcut that appears adjacent to the "Card" shortcut and below the search bar does not carry over when the text is enlarged. The only way to make self checkout available to visually impaired patrons with large text enabled is to rely on the "Checkout" menu item with the visibility set to "Always" or "Post-Login." (My library prefers the visibility set to "Pre-Login" so we can bump up a menu item for greater prominence since the "Checkout" shortcut makes the "Checkout" menu item redundant once logged in.)

Also, the graphics completely disappear when they could provide strong visual clues and tap targets for patrons with visual impairments.

I would like to see the app retain all components even at large text sizes. Currently the large text version of the app has distinct feel of "less than" when compared to the standard version. It would be nice to see the versions have greater parity.
