My most specific use case is my phone uploads. There are a bunch of random stuff (serial numbers, parts and other random things I only need for a few minutes) that I would just assume not be on my plex server. Is there a quick way to delete it from the server using the web client (or other clients)? If not, I’ll post a feature request.
I found it. For those who have this problem Server Settings > Library > Allow Media Deletion
Take a look at this page for how to do this. It isn’t made clear on that page, but when you enable the media deletion function, only the server owner can delete content. That means the account logged into the client app must be the same account that is logged into the server.
