I don't do regular housekeeping of my trakt data and things are prone to get messy due to various bugs in apps and plugins but I'll always end up with duplicate plays at some point. Many of those end up going from check-ins to plays at the same timestamp which shouldn't get accepted as valid by the site at all imho or at least end up getting merged. Despite not not being advertised outside of some support threads and a single kodi forum thread I end up getting a lot of visitors on my duplicate removal script (500+ last year) which tells me this is quite a common issue and affects plenty of people :/...

I love trakt. And I love TMDB. I contribute a lot to TMDB and think it is much better of a site and a community and more user friendly than TVDB. I understand that TVDB probably has a more comprehensive database for series compared to TMDB (I think TV shows are only a fairly recent addition to TMDB). However, contributing to TVDB is much more arduous than to TMDB, especially when it comes to getting incorrect data changed. The TVDB forum is fairly dead and slow to respond, me as a user have no idea if they keep track of our contributions.

Anyway, is there any reason why Trakt doesn't use episode information (especially air dates) from TMDB if they don't exist on it's respective entry on TVDB? Could this happen (any time soon- i.e. in the next couple of years)?

I noticed the other day that episodes in Season 3 of the 30 for 30 series have had their order shifted. Unfortunately, I can't tell what episodes were shifted where because TVDB doesn't show that info.

When it comes to Trakt, watched date/time and ratings that applied to an episode are now on the wrong episode. This caused episodes that I hadn't watched to be marked as watched and given ratings that I applied to the other episode. Some episodes seemed to just move ahead one or two places, but others I can't figure out. As an example, I watched episodes 12 and 14 but they aren't set as watched and have no rating. I didn't watch episodes 27-29 but they are set as watched and have ratings.

At this point, I'm trying to figure out what episodes I watched when so I can make sense of the shift but the season has aired over 3 years and I have watched episodes out of order.

I'm not sure if this is anything that can really be prevented on Trakt's end, but it is an odd situation that may need some attention if viewership, ratings, etc. actually got shifted for more viewers than just myself.

I use the trakt site a well as the SeriesGuide app on Android to input views manually.

The same way there's now a fast switch for dark mode in the main menu (Dark Knight Mode), I think it would be interesting the have a quick method to turn spoilers on and off. For example, when browsing lists, specially when there are lots of special episodes, sometimes I need to click on several items to reveal their titles, because "Special 34" doesn't give as much information as "6x03", and it becomes tiresome pretty fast. Going to settings to temporarily turn spoilers off and later turn them on isn't ideal either. I think a switch where a single click is needed would be fantastic.

As of right now you can mark a item as collected with one type of metadata bluray/dvd/digtal ect.
Myself I have multiple editions of a movie like a bluray and a dvd or bluray and digital copy or all of the above.
It would be nice to either be able to mark a movie/tv show/episode as collected more than once.
Like watch history with a view all button and the best quality shown on the main page.
Or be able to select more than one option under format.
I personally prefer the former because it represents what is an entirely different copy.

Hope this makes sense.
