I've been experiencing a strange behavior after upgrading to Version 1.0.0.2261 of Plex Server for OS X.
I run the Plex server off my iMac (running on Safari Version 9.1.1 (11601.6.17) and OS X El Captain, 10.11.5), which has its screensaver set to 1 minute.
Whenever I use the cast menu on the Plex Server to connect to either Roku or Apple TV, the screensaver never on my iMac never kicks in as if the computer was kept "awake" by something.
Reversely, if I play any media from the iOS app into my TV or use the native Plex apps on either platform, the screensaver on the Mac works just fine.
I've been using Plex with this exact setup for years so it took me a while to narrow it down to Plex (at first I assumed it was an OS X issue).
Anyone experiencing a similar behavior?
Any help appreciated!
