Hi, I've been using Cathe live on my iPad since the beginning. I decided today to switch to on demand using Roku. I have 4 different Roku models. I linked the one in my workout space. It was successful. Each time I try to play anything it briefly shows the title and "retrieving" then instantly goes back to the title page. I don't know what I'm doing wrong. My Roku says my signal strength is excellent and I just updated it moments ago. Any idea why it appears and then suddenly won't load?
