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description but after logging into ESPN, adding a custom ESPN league doesn't show what the video shows but rather the outdated create custom league screen.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.
Terrific addition to 4for4 tools! The extension works great to sync rosters with my 4for4 account. Great job working with the ESPN beast!
Recent update functional for 2021. Working great for espn. Love 4for4.com
