All the Roku units are very slow. From the streaming sticks to the Ultra. Maybe it’s the providers. Like Disney takes 30 seconds to load then it still has to load Indiv titles and watch lists. Adding a cache to speed it up would be great. Or background app running so it’s not completely relaunching each time. Lately I have just been not using the roku and watching on my ipad because apps load better and faster. It’s a huge difference in hardware but I think something running one app at a time could run faster. Especially the ultra that is not much faster.
