plex update 1.0.15

Just installed the Plex 1.0.15 update though the update manager.
However, Plex server is still on version 0.9.16.6; even after a reboot of OMV.

I am a Plex pass member, but I follow the public releases through the update manager.
Normally these updates work fine; however this is the first major version increase.

now I remember:

possibly related to:
enabling plexmediaserver makes OMV GUI unresponsive

after apt-clean, a new update appears (I already installed 1.0.15):
plexmediaserver 1.0.0.2261-a0117e99e-debian
Plex media server for linux, 95MB
maintained by Christian Svedin
repo: omv-extras.org-plex-mirror/

Can I install this one?

after installation of plexmediaserver 1.0.0.2261-a0117e99e-debian through the update manager
plex.tv server settings reports: Version 1.0.0.2261

and

I think this means everything's correct now.
My sincere thanks to you guys.

well, it appeared to work, but then I had the "will not play" issue mentioned here
Plex issue...

Disabling the plugin, re-enabling the plugin and waiting ~3hours (the time it takes to enable) solved it

I always thought the re-enabling just failed, but after the remark of @gderf to "get a meal" after clicking enable, I finally waited long enough.
During this ~3hours enabling, OMV stutters a bit and the user is is thrown out of the OMV GUI after that timeout, so this process is not very user friendly.

For years I stayed away from the Plex plugin enable/disable button, maybe an informative description next to this button "do not despair, enabling can take hours" would be useful?

I have no idea how large my Library\..\Plex media server\Media is because I can't get a result from du -hs before the Shell In A Box timeout ..
I'm guessing photos and series episodes take up more space than movies because each file has its own thumbnail.

I was wrong. Shell In A Box showed a result (while logging me out in the background)
This is the Library\..\Plex media server\Media division:
