I've installed the PPV plugin. It works really well for our Live Streaming service but one problem is the length of time viewers get. At the moment when someone pays £1, they get access to the streaming page for 24 hours. We want to charge £1 per game. The problem is if they pay £1 at 7pm on a Friday, then we have another game at 5pm on Saturday, they get access for free. Is there a way to reduce access to the page for hours instead of days?
