As with every major iOS update the Apple Pay Suica UI gets a minor tweak or two. Sometimes they pan out, sometimes they don’t. The dynamic commute plan ‘Renew’ button was a little more descriptive in b4 and b5. At best it’s was of questionable value when the language was Japanese but downright embarrassing to look at when the language was English.
Since Wallet card UI elements can be dynamic why not highlight the expiration date in red instead? Apple engineers fortunately had the better sense to change the button label back to the sensible iOS 13 design in iOS 14 b6, the final design.
watchOS 7 Suica is getting some useful tweaks: card transaction history, low balance and commute plan renewal reminders, and Suica card information can now be viewed and/or set directly on Apple Watch. In watchOS 6 these can only be viewed or set in iOS Watch App.
