The padlock icon on this in-app purchase list item was intended to reflect the puzzle pack state, but it often caused confusion. Sometimes a purchase would fail and the user would ask: Is the pack locked? Do I need to unlock it to buy it?
The alternative was to mimic the buy button style from Google Play, giving us the illusion of tighter integration. Now the purchase flow feels like it starts with puzzle pack selection, rather than in the subsequent pop-up dialog.
The resulting layout is cleaner and more familiar. It removes a source of confusion in the worst possible place. It’s a neat example of a high impact change from just a couple of small layout updates.
