All the episodes of the new season are doubled up and after the first ep they don't work at all.
I haven't got access to my NOW playback devices at the moment, but have you tried both duplicated episodes after the first episode ?
Just in case one plays and the other doesn't.
If neither duplicated episode plays across the entire season 3 then report it to NOW either via live chat or message them from this link below.
Hopefully one of the duplicated episode across the full Season 3 will play on your devices.
