Publisher 404 / Standalone Player

My ultimate goal is to only use the current (latest version) Web Player on Not looking to publish content through WordPress right now.

I first installed the Player plugin and it worked, but is clearly an old version. Then I installed the Publisher plugin and all podcast posts were being routed to a custom 404 page. Attempted to resolve this through settings and documentation, but to no avail. (It’s probably a bit over my head.) I couldn’t fix the 404 issue, so deactivated the plugin and attempted to manually install the Player through code, but couldn’t follow the documentation of how to integrate this into WordPress.

So, is there a way to use the Publisher plugin on my site to access the current version of the Player without it routing current podcast posts to 404 pages? Thank you!
