This has been working until now, but last few days I can add videos from YouTube to my queue, from within my browser, Safari, and it appears to be happening and I get the message back that it has happened. However, if I turn on the TV, go to Roku/Plex channel, the video is not there. I have tried several times. I am using Yosemite, OS 10.10.5 on an iMac.
Thanks for any help.
