it's still an issue for me. I subscribe to Criterion Channel and Arrow player -- which are great. But their stuff never shows up on Up Next. Paramount+ and Hulu do. Amazon Prime does. Tubi does. Plex does for their stream content, but not for your personal library. I want ALL the services to use it but it's never gonna happen alas.
