I believe we are completely at the mercy of the Plex team due to our collective stupidity 
Given this development, I’m going to try to share a DSM 7-compatible SPK today.

You will be our Hero !!!
Def our saviour, just to add that emby is gubbed aswell, you would think as part of the work synology is doing they would attempt to work with the 3rd party vendors.
You are TRULY AMAZING!
I’m only amazing if it works without my fingers ever leaving my body 
as a workaround i want to share what works for me:
connect to synology with ssh/telnet
type:
sudo /var/packages/Plex\ Media\ Server/scripts/start-stop-status start
now plex was running again
Are you using the preview of DSM 7.0 ?
If yes, it’s a great news !
Thanks
yes using DSM 7 preview
Yes, I can also confirm:
- Manual start of the package does work.
- Only the INFO file and
conf&uiinterfaces are incompatible.
It would be great if we can have a dev spk, my plex was in stop mode when i put on DSM 7 so not sure if thats why when i try a manual start it doesn’t work.
Its unclear what the update did to those packages deemed not compatible and in my case stopped.
An interesting note, their site states:
DSM 7.0 Preview is not available on the following models. But don’t worry, these models will join the upcoming DSM 7.0 Beta or DSM 7.0 Official.
FS6400, FS3600, SA3600, SA3200D, RC18015xs+, DS1520+, DS920+, DS720+, DS420+, DS220+, DS220j
which user did you use ? root ?
I got 2 error messages :
- line 18: /user/syno/sbin/synoshare: Permission denied
- line 22: SYNOPKG_TEMP_LOGFILE: ambiguous redirect
Did you reinstall Plex after upgrading on DSM 7 ?
Thanks in advance
If possible, I would like the DSM 7.0 firmwares for the following NAS devices :
- DS1513+
- DS918+
- DS1019+
Thank you so much.
Again, no promises. I’m finding a new burp in this version of firmware but am doing what I can.
For those of you who aren’t aware, the entire process control executive has been changed. Linux desktop users will know this as "init -> systemd" which does represent a substantial overhaul.
Yes I did it with sudo so I changed my former entry. And no I didn’t made a reinstall just started it on bash
Thanks a lot
I forgot the ‘sudo’ 
Now, Plex is running 
thanks !!
Thx! You saved my life 
Thanks @noyse! This works perfectly while waiting for an update by the Plex team
