A MAJOR Single-Sign On update has gone live on iOS 11 GM, it looks like. Basically every single major cable and streaming tv provider available now, including AT&T UVerse, Verizon FiOS, Comcast XFINITY, Cox, Spectrum, Hulu, PlayStation Vue, YouTube tv and Google Fiber. Also, a LOT of small providers. Looks like Apple’s delivered on this feature - albeit late.
Better late than never, though!
