The duplicate badge was removed from the media details page in 4.53.0 (announcement).
As of 4.56.4, it is no longer available at the library level.
Please restore the badge, at least at the library level.
I have some libraries where duplicates are desired for some movies (multiple resolutions/encodings/etc).
I have some libraries where duplicates are undesired.
Having the badge at the library level is a quick, easy, visual way to see if duplicates exist, and, if so, how many.
Using the duplicates filter is not nearly as useful, especially for libraries where some duplicates are desired. First, there is no way to list movies without duplicates (that I know of, anyway). Therefore, I have to open a second Plex Web window, one showing all movies, the other showing duplicates, and compare the two. Having the badge at the library level is much, much easier. Second, without the badge, there is no way to see how many duplicates exist without going into the details page for each movie. I know how many duplicates should exist for a given movie. The badge makes for a quick, easy visual check across the entire library. For example, if I saw a badge showing three versions, I knew something was wrong and could investigate. This is much more difficult without the badge. There is no visual indication of the number of duplicates, so I have to go to the detail page for each movie, a much more time consuming process.
Again, please restore the duplicates badge. Iām not sure why it was removed. I saw no posts of people complaining that it exists. There are several posts of people complaining now that it is gone. I personally find it very useful and would appreciate its restoral.
