My Roku Device is a new Streaming Stick 4K with software version 11.50 Build 4235-CU, up-to-date. I'm often given the option for adding to Save List and sometimes to Watch List. For example, with Gunsmoke in Pluto, I can select or deselect Watch List. With it selected, I can't find a Watch List anywhere. There is no option to add Gunsmoke to Save List which I can easily find in What To Watch, the second row down. This is obviously a software BUG that needs fixing.
