When I watch shows or movies then look back in to my history the programs consistently are listed as viewing twice. In order for my viewing habits to be correct, I would have to go back years and delete the second (and sometimes 3rd and 4th) listings of tv and movies I watched once.
Are you using an app or media center? If so, this usually means there are 2 instances running or 2 separate apps that are both scrobbling.
I quite often check my History as I find this happens too.
My first thing to check in the History page are the 2 sets of numbers to make sure they are the same.
If not then I then look at Episodes in the drop down list
I then change Recently Watched to Most Plays and this shows any duplicates
I can then go in to each one and remove one of the views (hopefully if kept on top of there are not too many).
Hope that helps.
As you might see I currently have an issue where almost 1400 duplicate items have suddenly appeared on my History. Hopefully an answer will be forthcoming as to why from the ticket I have raised as to why this has happened.
That is just WAY too much work
I’m watching in Syncler
Ok, please contact the 3rd party app developer since that sounds like a big with their app.
