STM struggles with yearly Opus problem

People using the Opus à l’année system were invited to suspend monthly payments for the pass as of April, but there’s no mechanism to deauthorize the cards remotely, so lots of people have gone on using them. Now some users, unaware of the situation, have bought tickets for occasional use and continued using their card, and have received warnings because the STM’s machines have preferentially tapped the yearly pass still on the card instead of debiting the tickets.
