Good info. Thanks!
I've always suspected that some of the larger and more complex channel apps, like Netflix, just keep a smaller stub in memory on the individual Rokus, and download the balance each time they load.
@makaiguy Sounds like a logical explanation to me. And with each major change the Roku makes with their OS also forces the app makers to adjust how their apps operate too, which may or may not play well with each other.
Possibly. What is strange in my case is that on one of my Rokus I get the "Loading..." screen on YouTube TV. On another, it is on Prime Video. So it isn't consistently the same app between devices.
