Last night's episode hasn't been added yet to TV Anywhere. This is Series 6, Episode 4.
Following on from my comments in the Da Vinci's Demons thread, this is a perfect example of the flaws in Virgin Media's delivery of on demand content online. Walking Dead aired last night on Fox at 9pm followed by Talking Dead. Walking Dead was added to TV Anywhere after airing, whereas Talking Dead wasn't and still hasn't been. Both episodes were added to Sky Go online last night after airing. Sky seem to have no problems delivering on demand content from all providers promptly after airing, yet us Virgin Media customers are given an unreliable/unpredictable service.
Please get this rectified.
