[Pay Per View] Pay Per View Plugin

Yesterday I had an issue with the one-time access pay per view option. I originally had the duration set to 1 hr, thusly my customers were only able to view the content for an hour after they made their purchase. I since then update the duration to reflect 24hrs. Hoping that would rectify the situation, however it did not. I had a user test it out for me - they made a purchase, started watching the film, paused it, then closed his mobile browser, can back 2 hours later but was then forced to pay for the movie again. I thought that if I updated the duration to 24hrs that, that would solve my issue....
