Why did my Seoul bus-to-subway transfer discount fail?

I tapped in correctly but paid another full fare. What are the common tag-off and transfer-window mistakes visitors should check?

Always tag off the bus, then use the same transit card for the next ride within the applicable transfer window.

Two people sharing one card cannot receive normal individual transfer treatment; each traveler should use a separate card.
