I have FIOS Internet, and can access ESPN3 on my desktop but not on my ESPN or WatchESPN apps in my Android phone or my laptop.
For my laptop:
--Browse to espn.com
--Click on Watch
--Brought to place to select Provider
--Select Verizon FIOS
--"ESPN subscription required...Shop Now"
ESPN3 is free for Verizon FiOS users; no TV subscription is required. It is on the list of approved providers (http://www.espn.com/espn3/affList).
Also, after tinkering, I am able to view the ESPN3 on my desktop.
Finally, I had to problem in the past on any device.
I've tried different browsers, turning off my VPN, and in Incognito mode.
Any tips? Thanks
