Thanks for getting in touch. To force a one-time refresh, you can clear all of TubePress’s caches at any time by following the instructions at the bottom of this page 1. We always recommend enabling and adjusting your cache expiration lifetimes 2 to the highest values that you can tolerate. Shorter cache expiration times will allow updates to your playlist to show up more quickly; however, this also means that your site’s performance may suffer somewhat as TubePress will need to keep checking for changes. If you don’t anticipate frequent playlist updates (i.e. more often than every 6 hours) and you can accept a 6-hour delay from when a video is published until when it shows up on the site, then keeping the six-hour default (21600 seconds) is perfectly reasonable. Please let us know if there is anything else we can do to assist!
