Thanks to the latest tvOs update, it now seems possible to use my iCloud Photo Library as a screensaver. However, I'm unable to get it working. Whenever I go to the screensaver selection menu and choose and iCloud Photo Library, it just lets me select a single photo and just shows that on the screen, nothing else. I cannot go any further, so have to go backwards a few menus where I find that the previous screensaver option is still selected. Does anyone else have better luck?
