I notice when I turn on ipv6 on Spectrum account iTunes won't load anything and on my phone AM is slower than dirt just giving me gray boxes after a few minutes slowly loading artwork. This has been going on for three weeks now. Not a peep anywhere from Apple or Spectrum. I even hooked it up directly to the computer and it won't work with ipv6 connecting. I also changed DNS even using the native DNS still does not work.
Also if I turn off ipv6 through my router my cable modem gives me no such option then iTunes and the Apple Music app loads fine.
