Choose where the auction is, then tap Bid or Buy now on the auction page. The right phone shows what opens straight after the tap. Live Bid has four possible answers because the bid is processed on the tap.
Pick a state. The push on the left and the trip card in the middle both carry the headline for that state; tapping either opens the screen on the right. Opening the app cold lands on the home page in the middle, never on the screen.
Read left to right. Solid arrows are taps in the app, the screen opens immediately. Dashed arrows go through a push or the home trip card, so the screen only opens if they tap. The right column shows which of the two templates each state is a variant of.
