Hi there,
I'm not sure what the term is exactly but when you are watching VOD, you will have the red progress bar that shows how much you have watched or which episodes you have already watched. It's an awesome feature especially when watching TV shows as you can come back and easily see which episodes you have already watched but i've noticed that many times the indicators are reset and all episodes show no progress bar.
Just wondering what would cause this or if it's a known issue.
Thanks
