After some testing, we found that restarting your casting session seems to help. We also suggest that you select the program you wish to view, begin playing the program, and then cast.
Right now, Autoplay is not functional while using Chromecast. To continue to the next episode, stop casting and select the episode you are ready to watch. You can then restart your casting session.
If these methods don't solve the issue, please contact us through our 'Submit a Request' option so that we can help!
