Weren't you able to download contest history in the past? Is that feature still available but moved/hidden? I'd rather not go throught 2,000 pages of information to figure out my winnings for the wonderful IRS.
This certainly was a feature in months past. As recently as the latter stages of the 2016-17 NHL/NBA season, I was able to download my full contest history, then upload the file to a "bankroll analyzer" offered by a DFS advice site. I don't see that function anymore, but I think it should be made available to users again (especially if Yahoo is committed to responsible gaming; users ought to have an easy way to see just how much money they've spent in order to make safe money-management decisions going forward). Please consider bringing the feature back.
