I would need direct confirmation from someone on here before I believe it. There are pics from one person online stating it happened but others have had no issue so it seems more to be a bug and the people are not being detected in friends and family.
I've asked my mate if he needed to pay anything, and he's said he hasn't, but the ticket won't be available to download to his Google wallet until 3 hours before kick off, which is different to last year. That shouldn't be a massive problem, though, as long as he isn't expected to pay anything to release it? I've no reason to think that will be the case though.
My understanding is that you would only need to pay if you were in a different price category - so a child ticket going to an adult, that kind of thing. That would make sense.
