While they did not contact us and let us know anything was changing, I think it's possible they have killed off the old method we used to export directly to Fanduel. I am going to look into it before absolutely making that determination, but I had to believe this would happen sooner or later.
We do now support the exporting to a CSV file, with the correct FD player IDs, which is actually considerably faster if you are doing more than a handful of lineups. Previously we were limited to exporting 1 lineup per 2 secs previously, so 60 lineups would take 2 minutes to fully export. This is not an issue with the CSV method.
