I'm new to this forum... finally given up on the newly redesigned non-user friendly official Dish forum.
I also had the same issue last week with The Terror. This has been an ongoing issue with various shows and channels that I have been reporting to Dish for almost a year now. Timers arbitrarily can't see new episodes in a series even though all the guide info is correct. Timers are so unreliable that I have to check every day or I will miss shows that I have set to record.
