Server Version#: 1.23.4.4712
Pre-rolls stopped working all of a sudden on all clients. I tried on the shield, the web player, and my android phone. I verified no settings were changed anywhere. I can browse to the pre roll videos directly on the windows server that PMS is running on and I have tried restarting the PMS hardware/OS. Any known bugs on this? I can upload logs if needed. Thanks for any help.
I believe this has been acknowledged.
I just applied the update to get to version 1.23.4.4775 and the pre-rolls are still broken. Anyone have any ideas?
Just updated to 1.23.4.4775 tonight, and Prerolls are working in browser/webui players, but not in any apps (android player). Just adding info.
As of the update 1.23.4.4775, this still has not been fixed. I had rolled back my updates to 1.23.2.4600, and they were working again. I didn’t do any special scientific method for choosing that update. I just knew it was working after the end of May when that update was run, and tried it out. Voila. I won’t be updating to any new versions until I can get a definitive answer that any of the new updates have it working.
Great sleuthing! I’m surprised more folks aren’t posting about this error.
I know of a lot of people who Plex, but aren’t using PreRolls, so that drastically drops the number of people who are affected by it. It took me a few weeks just to find the time to play around with it. In the end I was like, “This is around the time when it worked”, and picked the nearest prior update to see if it worked. It did. I will provide the obligatory “BACKUP your Plex server before doing this” just in case someone does something they aren’t supposed to or has a different setup for one reason or another, etc.
Just applied the update Version 1.23.4.4805 and sadly they are still broken. 
Just adding onto this as well for exposure. Would love to get this feature back working.
1.23.5.4801 on Linux still broken.
Just chiming in pre-rolls are definitely broke.
@Pittsmaster You may want to tag additional platforms in this since I’m pretty sure this is a cross-platform issue - that may give it more visibility.
Tagging a Ninja may not be a bad idea either - @OttoKerner (sorry, you were chosen at random lol)
I only care so much about this feature because it lets me advertise to users the ability to change the quality of their stream with my pre-roll - without that users settle unknowingly for the default 720p - and the other solution for streaming quality is taking…a while.
FYI - Windows 1.23.6.4810 still has pre-rolls broken. Odd that this is getting no love.
just downgraded my unraid docker version to 4707 and pre-rolls are working again
docker pull plexinc/pms-docker:1.23.3.4707-ebb5fe9f3
I can verify 1.23.3.4707 is the last version where pre-rolls work as intended. any version after that needs 1 cinema trailer enabled first and the pre-roll plays right after the trailer(s).
1.24 it will hopefully be fixed on.
I also create Pre-Rolls to send messages like when I am planning to take Plex down for hardware upgrades, etc. Came in real handy when I had moved, and I had 2 weeks where the preroll let people know that the server would be down for a day for the move.
I used to do that, but I’ve since moved to using statuspage.io by Atlassian and just have my users subscribe to it for updates.
If you only want to play the preroll, you can disable all trailer in the server settings, and set the Plex player to play 1 trailer before movies.
This may be resolved in 1.24.0.4897.
