Just checked on my Now TV Stick and as you point out there seems to be dozens of The Walking Dead episodes missing from across all 8 seasons...... I would guess this is another of those temporary glitches that needs to be fixed.
@Anonymous User @Anonymous User Just to advise, the catch-up boxsets for The Walking Dead that have been uploaded Today seem to be missing loads of episodes across all seasons....... you might want to get the Tech' folks on to fixing this.
Thanks for that update on The Walking Dead episodes.
It may be part of the same issue..... but there was also another very recent thread on the forum about many episodes also missing from The Wire boxsets that were uploaded recently...... it may also be getting worked on but just thought I'd mention it.
