How does the duration of access work for paying viewers?

The duration in the paywall works like a rental time from the moment they start to watch.

For example, if you enter 30 minutes as the duration it means the viewer has access for 30 minutes from the minute they first watch. This continues to countdown if they continue to watch the stream or not. So if someone starts to watch for 5 minutes, leaves for 25 minutes and comes back to watch again, their original 30 minutes of access will have expired.
