I have added the markets to "Cart" and attempted to purchase, but it brings up a web page with the message "Order not found or completed already". Nothing has been deducted from my Betfair balance. Any advice, please?
Also, I cannot seem to manually download purchased data for select sports/markets; instead, it wants to download my entire history from over 10 years ago. But I remember that back then you could download individual markets of your choice from purchase history rather than having to download everything.
The main issue is the inability to purchase custom markets any more.

Any thoughts on these two issues? Thank you so much - Chris
