Playlists not pushing to Plex

[genrl]

Hi, this seems like a great tool and everything seems to be working on my local side and the GET from Plex, but I can't seem to push anything to Plex. This is a new library, running Plex as a container on Raspbian/OMV. The script runs end to end without errors, the working folders are filled with all the playlists for Local, Temp and Plex whilst the script is running. The token works and the test playlist I have on Plex is grabbed and merged (albeit with duplicates each appending each time) to a local playlist successfully. I'm running PPP from a Windows machine (Python 3.9) on as admin and there are 'everyone rwx' rights to the working folder, which is volume bound on Plex container. In the Plex logs, there seems to be only a GET on Plex and not much else. Sorry to be posting here, I've looked through all the open and closed issues and just wondering if anyone encountered this or has a way for me to trouble shoot? Seems like a great Google Play Music substitute that I can use in conjunction with MusicBee.

Huh, my only thought is to check that the playlist that was successfully synced with Plex looks exactly the same as the other ones you're trying to sync. i.e. same file format, headers, text encoding etc.

I hate to recommend something completely different but if you still can't get PPP working, I recently released ultrasonics, which has all the functionality of PPP plus a load more. You can set it up to sync between Plex and local files in the same way, maybe whatever is causing your issue won't be a problem with ultrasonics?
