I had the same problem, so rang the club. Told me they have a major ticketing issue with their Android Service Provider, and Android Season Tickets for tomorrow have not updated. I followed all their instructions, but not succeeds.
They will issue a replacement by email if you phone up (and they've done that for me) but they have decided not to email supporters to inform them because they can't target Android users. Utterly ridiculous decision - would be better to email everybody and explain this only impacts Android users. As it is, Android users who haven't checked their wallet and sorted this in advance are going to have a problem. Everyone can expect carnage at the turnstiles when thousands can't get in.
