Is there anything that we can do about duplicate plays from using Plex Sync? If I do a complete sync of my Plex library I get about 8000 plays added to my watch history and almost all of them are duplicates. I rolled back this sync.
I did a new sync and added 119 plays and all of those are duplicates.
@justin Things so far have been working better, but does plex sync not handle going back and retrying skipped items any or something? I ended up having a scan that got complete while my plex library was still working on scanning stuff in and one of the seasons of a show was messed up so it got skipped in the scan (the episodes ended up under the skipped items section) due to that, during the next scan which happened about an hour later I had already fixed the season and all that in my plex library but it didn’t scan in the fixed stuff at all that was skipped before, only anything new I had added (which was a new single show) was scanned in. I ended up having to go and set up PlexTraktSync again to scan the fixed episodes into my library.
I have a problem with the Plex Sync. It doesn’t work anymore. last sync is from 10 sept 2025 10:15 PM. I have undone all the syncs, disconnected and reconnected plex. But it doesn’t matter what I do, I don’t see anything getting synced anymore. When it was syncing, I got already marked watched episodes and movies marked as watched 2 times.
Also got this line: “No Plex libraries found! Please add at least 1 library to your Plex media server and also verify you have remote access enabled.” Where I have 2 of my libraries selected…
Why is this called Plex SYNC if it doesn’t remove collected media after I delete it from Plex? Now my Plex library and my collected content on Trakt are way out of sync.
FYI, I am out of the office next week so I won’t be working on plex sync or responding during that time.
I’m working in phases. The first phase is syncing from Plex to Trakt. The next phase will include things like removing from library and syncing data back to Plex. I do have to be careful with deleting library items though. If I get no or bad data from Plex, I would want to just blank out your Trakt library for example. This would for sure be an opt in setting.
I think the check for this needs to be more broad on the Trakt side. Currently it looks for an exact timestamp match to determine a duplicate.
I will have to think about this more. Right now it just stores a single timestamp, set at the end of any successful sync. I might need to store individual timestamps (history, library, ratings, watchlist) and perhaps use the start as that saved timestamp. That might allow it to pick up items scanning during the Plex sync.
Plex Sync appears to be adding duplicate plays that have already been registered with the webhook for me. I’ll have to disable it for now. Please can you fix it so it doesn’t add duplicate plays at the same time?
Does this happen even if the day is the same? That may be impossible depending on what my other tools marked as the time zone. I want to sync for the first time and have it add ALL my watches, but I’ve already used other tools in the past for my Trakt history and ratings (but only most recent watches). I wonder if I delete my entire history in trakt and start from scratch to run this sync. I’ll run a sync and see what happens. It’s nice that you can rollback.
Update: I had a bunch of duplicates as well, some even that had the same exact day and time. I just deleted all history, library, and ratings and then did my IMDb –> Trakt sync tool then Plex Sync. Should get all my history and reduce most of the duplicates. I still run PlexTraktSync for any missing directionals.
When I mark a title as watched in Plex, that should be picked up by withplexsync, right? But I still don’t see the titles I marked as watched in the past few days showing up as watched in Trakt. There have been a few syncs in the meantime.
This might be a silly question, but have you scrolled down on the PlexSync page and selected what you want to sync?
If you are manually marking them as watched, you may have to do a manual sync as this is still in Beta and Justin is away this week.
Do you have your settings set so only one service (PlexSync or Webhook) are syncing for “watched” plays? This should solve duplicating your watched history moving forward.
Justin has just addressed the issue of duplicates showing up, and he’ll work on it when he returns and has had time to think it over.
Remember, this is in BETA, and there are bound to be bugs, that’s why we’re here. 
Well said. People getting all worked up and frustrated over a Beta feature that’s developing nicely is strange to me.
Ah I didn’t realise there was that level of granularity for sync vs webhook. Thanks, I’ll update that.
Is anyone else seeing issues with new library items being correctly added by Plex Sync but not showing as collected when viewing the latest additions to the library. I can solve it by refreshing cache but haven’t had this issue before when I was running the webhook to pick up new additions. Now I’ve switched to only Plex Sync this seems to have popped up and is reproducible for me.
The following error message when I try the Plex-Sync:
Plex Server is connected
’user’ option is blank
”No Plex libraries found!”
Can you try this, click the Disconnect, clear browser cache and resign in.
There should be a name under “User” and its not rendering for some reason.
If the above advice doesn’t solve your problem, can you hover your mouse over the name of the server? That will show the connection path it’s trying to reach. If you use a non-standard port it will probably show it’s connecting through port 8443 which occasionally seems to take a while to bring up the user name dropdown box. Usually a refresh and patience solves that for one of my servers that has that issue too.
After the fix was pushed last week, hourly syncs were happening. But a few days ago no more sync are happening and even a manual sync does nothing. Tried a bunch of things to get it working again (changing port, disconnect plex and reconnecting, changing some network setting , rebooting my plex server, ..) but nothing helped.
Just a note here for @justin when he returns. In my sync today (9/18 - 11:08CDT) Plex Sync accurately picked up the addition of Black Rabbit - Trakt to my Plex Watchlist and imported it, but failed to also import it to my Library. I had to manually import it.
