they keep making you get the number of the screen go to your computer and type it into that page again. I had to do this about 4 times.
They will show you one a relevant ad again and again and again
Every time you try to rewind because you missed a bit of dialogue, it makes you watch another round of the same add a few more times, and because you can't find exactly where you want to be so for sleep, you may need to rewind and fast forward 4 or 5 times and every time you do they will make you watch the same ad a couple more times.
I would rather pay a few cents a day and gets a brilliant service like Disney or Prime
