I just updated to the latest plex server and I see now you "have to log in" just to stream content over your own local network. I went back to my timeline back up and pulled the old app out of my last backup and don't think I will be upgrading or will be finding a new local server wide solution. I think it's a bit ridiculous that now I need to sign into the online site to use it locally. Just food for thought if anyone else has this issue, goto your backup and grab the old app.
Anyone see the "last modified date" of the new version, it's a wacked out old date.
Just my .02 cents...
