Hi,
Yesterday, by mistake, I deleted all my Plex Libraries on macOS Sierra.
Everything was working perfectly so far.
I had to reconfigure all the libraries. Since then Plex is not playing some (a lot of) movies or TV shows as before - even in the same library, neither on the computer itself nor on my iOS devices.
On the iOS devices I get the error "Couldn't create playback session for this item".
None of my disks are full, transcoder disk has 500Go left, which is more than enough, and permissions have not changed since I accidentally deleted the libraries.
I even reinstalled Plex.
I have tried all the solutions I found browsing the forum, so no need to lecture me with things like: "Please search the forum before asking that question". Done it; found nothing useful. Now I'm pretty pissed off.
I'm using the latest release 1.2.2 and I have a Plex Pass.
Thank you for your help.
