They have noticed now and removed next Sunday's episode from the hub. To clarify, on the weekend before last, Jekyll and Hyde was not shown because there was a shoot-out scene in that episode and it was deemed inappropriate the day after the events in Paris. However, the episode was made available on the Android version of ITV Player the same evening, presumably in error. The episode was not taken down until the following Wednesday. This episode was then broadcast last Sunday and, presumably in error, both this episode and the next one (now rescheduled to be broadcast next Sunday) were made available on the Android version of ITV Player/ Hub.
I wasn't making a complaint, just giving a heads up in case anyone wanted to watch either episode pre-broadcast.
