Everything in my Plex Libraries was added to the Collection function in Trakt. But I was not informed this would happened or a setting that I could opt out of that.
This was very confusing to me that those settings had anything to do with Plex Sync since they are below the Plex Webhook and there is other settings for Plex Sync above the Webhook information and when I initiated the Plex Sync.
The small icons on the right I had to hoover…
Not user friendly in my eyes…
But thanks! 
You can remove your Collection information. It’s rather simple and straight forward, but I can’t spoon feed you everything, so I recommend Googling it or better yet, search the forums you’re currently in.
Then go back, adjust your settings (that if they were a snake they would’ve bit you) and run your Sync(s) again. 
Again – everything here is reversible; Syncs can be undone and Collection/History data can be removed 
I’ll keep my comments regarding anything else to myself, good day sir.
Well it seems to have synced all the movie libraries fine but there seems to be absolutely nothing synced on the 3 tv series. Or any collections for that matter. Any way I can see somewhere what the issue is? Or check to see if that simply means everything I had in my “collected” list was already there? Although that doesn’t explain the lack of activity on the Watchlist as I intentionally added a movie to my Plex watchlist which doesn’t seem to have transferred over.
It allowed libraries to load and select a user. Still haven’t successfully run a sync though but definitely getting closer
Sync goes queued and then nothing, no email, no errors just doesn’t do anything:)

In the same boat. Connected and synced. States it’s queued, but nothing happens. Just unsure if I’ve altered settings on the Plex Server side that’s causing sync issues.
It’s not you, PlexSync is currently in Beta and it’ll take time for Trakt to work out any bugs, It’s getting there though.

Trying this out for the first time this week, definitely getting odd results (although admittedly I’ve not read this whole thread yet, maybe they’re not so odd?). Biggest standout is that history hasn’t synced at all. But it’s also odd that I got two apparently succesful (or mostly successful) syncs on first attempt, and then haven’t had any further successful syncs in the couple of days since (I’ve tried manually queueing and that’s not triggering anything either).

Just curious if this is syncing at all for anyone beyond the first time? Which isn’t even fully successful.
If it is and that unicorn user is also still using the webhook would that lucky person be willing to share their settings from the bottom of the Plex Sync page.
Also curious is ANYONE at all has even seen their watchlist be synced. I have 175 items in my Plex Watchlist currently. I have 141 items in my Watchlist here on Trakt. All were manually added / imported or using PlexTraktSync. There’s been zero items added.
And there’s been total silence. Again.
I responded 2 days ago and I have other tasks to work on in addition to Plex Sync 
Yes, in my several test accounts I am getting new data and watchlist data being synced over. In general, the Plex Sync is working for hundreds of users. I will continue to work through the issues reported in this thread, but it takes some time since each person’s setup is a bit different in terms of Plex media server version, how big your library is, etc and I need to look specifically at it.

Where is plex sync getting the dates from when adding stuff to your collection?
It uses the “added” date from Plex.
Hi Justin,
From my side, even with your latest update, I still have the message “No data has been synced yet.”.
We just have to be patient I’m sur this will be solved soon.
Thank you for your continuous work.

I see a sync from today at Aug 22, 2025 9:31 AM so it appears to have worked for you? The initial sync can take a while depending on how much data you have and how fast the connection to your Plex media server is.
It’s getting a 520 error, which I believe is from Cloudflare. Perhaps there are some logs on CF and some settings to allow connections to work properly. Another user mentioned “bot fight mode” was preventing their server from being reachable.
I made some progress here. I found out Plex has a different (or missing really) format for paginated results when pulling the watchlist directly from their servers (it doesn’t use your plex media server).
I made a fix for this pagination and was able to sync over 5 new shows to your watchlist. There are 23 skipped items due to missing metadata from Plex, so I am still looking into that part.
EDIT: I pushed a fix for the metadata issue as well. This added 1 more show to your watchlist. The other 22 found metadata, but were skipped because they already existed on your watchlist from what I can tell.
Appreciate that. Hopefully going forward it will sync.
But is this a case of metadata being corrupt / missing my end? Or missing from TMDB? Anything I should do or can look into to rename the files to make them match / sync?
No, it was an issue with getting metadata from Plex itself. As a test, please added a few things to your Plex watchlist (that aren’t watched or on your Trakt watchlist). If my fixes worked, they’ll sync to Trakt about 1 hour after adding them to Plex.
