ESPN3.com / WatchESPN - Why can't this ever work properly?

Trying to access ESPN's online streaming product through Comcast/Xfinity has become absolutely infuriating.

Why is it that Comcast/Xfinity can't seem to get the ESPN3.com or WatchESPN to set up properly or consistently?

Please note, WatchESPN is touted as a feature of Comcast/Xfinity.  After months of not being available... recently, it was announced that it was.

It works through the mobile app, but not on the desktop... which makes no sense.

When you go to ESPN3.com, you are redirected now to WatchESPN.

When you attempt to watch a program, you are asked to identify your cable service provider.

Comcast is not among the options.

Selecting "Not Found", you are asked to enter your zip code and pick from a list of cable providers.

Only then is Comcast shown.

BUT... ESPN then directs you to log in directly through Comcast/Xfinity

So, you go do that, and the only connection you get when you click on ESPN3.com through Comcast/Xfinity's page is a blog listing of the schedule.  

There is no apparent way to access ESPN3.com through Comcast... DESPITE THE FACT THAT'S WHAT ESPN'S OWN PAGE INSTRUCTS YOU TO DO.

There are direct links to ESPN, ESPN2 and ESPNU but clicking on ESPN3.com only takes you to a schedule listing... with no way to access ESPN3.com.

The process to get to, and the availabilty of, ESPN's online products on Comcast/Xfinity has changed seemingly month-tomonth over the last couple years.

...that's despite their constant advertising that it's available.

This is infuriating.

Anyone with Comcast care to comment or assist... for a change?

Am I missing something?

Help, for once?

(Note: I tried to post screenshots of each step along the way, but this interface won't let me.  Yet another technical disaster brought to you by Comcast/Xfinity).
