A new build was release yesterday as the October update. New features and changes. Edge now ONLY has the "Allow Once" for Flash. The ability to create an "Allways Allow" list has gone away and it is according to the roadmap that Microsoft created for Adobe Flash deprication over time as it is UNSAFE. Everytime I launch xFinity Stream URL in my browser I now get the Adobe Flash broken page and have to click twice to enable only for one session.
Either they migrate to HTML5 video format or they give us a Windows 10 app. 800 Million users on Windows 10. Its not going away.. I stream all day long on my 2nd Office computer while I work and on my Windows 10 tablet which ROCKS! I'm not going to watch on my iPhone. Size matters
