Same story here. Tried 3 times to print an elderly friend's ticket yesterday and, despite getting the confirmation emails, no .pdf ticket was attached. I tweeted Supporter Services and got a DM back to say Print at Home not available for Sunday for security reasons - couldn't I download to mobile? I pointed out he hasn't got a smartphone and that I have printed his ticket every match this season and this was the first I'd heard of PAH not being available for this match. They responded with 'if he has printed a ticket for every game, a paper ticket will be on the way to him in the post'. Well it's not arrived yet!
