The free view of the episode is not in any folder, but it IS AVAILABLE (SD and HD) via my legacy set-top box using SEARCH and the keyword "SI". Don't know what the X1 procedure may be.
I was able to watch it Friday night & I just checked that it is still accessible. The episode is labeled as "Available Until 02/09/2020", so a time-compressed version may post (correctly?) after midnight.
Hope this solves it.
Also, under the USA folder (via By Network) there are folders (SD & HD) for "Sinner", as well as "The Sinner". The new episode is only found under the latter. (One can only hope that the staff add a sub folder "You Sinner!" or "Repent, Sinner" in due course 😜 )
Welllllllllllllllllll..............
Episode 1 did finally appear to be seen for free.................about 3 days after the fact. Episode 2 finally became available today. Again days after airing. If I wanted to see what happened with each episode (before I see it) that can be viewed the very next day. UGH!
So much for on-demand viewing the next day after airing. I'll just have to be patient and wait. USA network not giving it up right away.
Sad to say that episodes 4 - 8 were available, but "short-dated" and have expired...back in April.
Very frustrating when Networks do this 😖
Another USA Network show Dare Me has episodes 1 - 3 available, others are PPV
The "inverse" also happens:
NBC's The Blacklist episodes 1 - 14 were available "short timed" while 15 - 19 are/will be aviailable until 09/20/2020
Same thing happened to us. We wait until a show has aired all episodes, and then watch one each night. Was keeping an eye on The Sinner, and finaly saw all 8 episodes. Went back short time later to start watching, and found that episodes 4-8 disappeared. Only available in "Search" as "Buy". Interestingly, "By Network", it still has "Inside Episodes 1-8" for free. This makes absolutely no sense. Same thing happened with "Evil" on CBS. The last two episodes disappeared and were only available as "Buy". Other shows are missing episodes. Right now, we're checking Yellowstone, which has aired two episodes. Problem: they're only in SD, not HD. Will we bother to contact Comcast? Why bother? If you "Chat" with Comcast, they say they'll give it priority, but nothing gets done. Comcast needs to do something about this for their customers.
