My biggest grief are the constant streaming interruptions which makes it unwatchable. I also experience the same interruptions watching CS on my smart TV. This has nothing to do with my Wifi. I can watch Netflix for hours and days without any glitch. I filed numerous complaints to CS only to be told they have contacted the developer. No further feedback or fix. I subscribed because it was on special offer. Now I know why. They knew they sold me a piece of junk.

I'm wondering what happened with the app? years ago it was fine but now downloads take forever and would usually fail. i also don't find the collections user-friendly, like there's no way to download an entire collection and you still have to open each video to click the download button and then you have to wait forever for it to download.

This app is terrible. How do you have a video streaming app that has no way of controlling the videos? It's common to get into a situation where a video is playing and you can't stop, pause, or control it in any way, other than just force closing the entire app. Also it claims you can save videos for offline viewing, but most videos don't have that option. And the ones that do, many don't work.
