Welcome to the forum. They are there, but you need to choose the right listing. If you do a search for criminal you'll find Criminal Minds listed twice, you need to make sure you choose the Sky Living one which includes season 13 (or alternately you can navigate there by going to Entertainment > Channels > Sky Living in the menu.
Once you've watched one episode it's quickest to go via your My TV > Continue Watching section.
Noticed on the ABC Studios section that Criminal Minds have two folders Season 11 is shown in a separate folder from the other seasons 1 to 10 then 11.
Any reason for this or could the NowTV Content Team put all 12 seasons in one place ?
Sorry to be a pest, my above post should have said seasons 1 to 10 then jumps to season 12.
Also noticed in the Criminal Minds Beyond Borders folder that season 1 episodes have been randomly added and don't seem to be in numerical episode order on the list ?
Where also season 2 episode 9 appears to be missing ?
We're aware of this, its currently being investigated, its proving to be tricky to locate the root cause. Luckily S11 is in the Sky Living folder. Not ideal of course but at least we can watch it (At my current viewing rate I hope to be up to Season 11 in about 4 weeks).
