PMS keeps pc awake even after quitting the app

Hi guys,
After I updated the plex samsung tv app (2014 TV model) to the latest version (2.006), it prevents my computer from going to sleep unless I restart the plex server.

It's 100% plex issue because when running powercfg /requests, it show plex as the process that keeps it awake.
I tried to downgrade the PMS server (1.2.7.2987) to a lower version, unfortunately it didn't help.
When streaming from chromecast, it doesn't happen so it seems to be an issue with the Samsung client.
Any known workaround / fix in the near future?

Thanks!
Ben
