FanDuel changes have stopped the browser extension from functioning.
We're hearing reports from users that the RotoTracker Sync browser extension has stopped working with FanDuel. We're investigating the issue. It looks like FanDuel has implemented some bot detection tools on its website which is blocking scripts like Sync from interacting with the site and downloading the files.
While we explore options our end, you can still download your file manually in the history section of FanDuel. Set the date range, and in the top right select "Download as CSV." That file you can drag-and-drop onto the extension, or onto the box on the uploads page on RotoTracker.
Sorry for the inconvenience, and we hope we have a solution to this soon.
