I watch it using Apple TV 3. Works great. I'm current on Windows 10. Seems to work fine on Internet Explorer, Edge and Firefox, but I haven't watched it there for any amount of time.
I use the Internet Explorer browser interface (cravetv.ca) regularly for managing My Cravings (favorites).
Firefox requires an Adobe flash player install and Edge requires activation of the embedded flash player.
I have used Crave with the chrome browser in the past but today I can't even sign-in.
