You mean the app works or the app is still letting you book tickets?
I paid yearly too. My plan was supposed to go from August 2018 to 2019. Watched 8 movies (16 tickets) so we broken even a while back even with the ticket booking fee haha.
Tried again on the app just now. This time I was able to get further than the "update your app" message. Was able to choose my card for the $3.99 payment but couldn't get past that.
