Think they used the app then probably got on or off at penn with no signal. If you get on around some of the underground locations definitely possible to lose connection before the digital validation finishes. I've had it happen once or twice when not wanting to miss the train.

It doesn’t become validated for a couple of minutes after you tell it to validate, so there’s no reason not to do it way upstairs.

You are supposed to activate it upstairs where the giant sign is, not on the platform level

Sure but if you forgot and your train is there I'd risk the ticket for the couple of underground stops. Especially when it's late and time between trains is longer.
