One of my favorite 4for4 services and they worked quickly and efficiently to get this up to resolve an issue on ESPN's end.

Update 9/28: Everything works, 5 stars Update 9/14: Adjusted to 3 stars per dev's reply, will update later on when there is a full release Original: Doesn't work, attempted with fresh chrome install as well. Followed video in description but after logging into ESPN, adding a custom ESPN league doesn't show what the video shows but rather the outdated create custom league screen. The extension then shows you're not logged into ESPN.
