The odd things is, the extras/featurettes do not appear in my browser client when managing my library, my LG TV nor my Amazon Fire Strick. But they are listed perfectly on my Plex android phone app (shown as “Extras”)?
Indeed, and I acknowledged that in the OP and stated which approach was suppose to be compatible with all clients.
Seems the issue was down to:-
a) Sub folders in the Featurettes folder are ignored. ie: Your extras have to all be directly in the series/featurettes folder.
b) Videos in Featurettes folder are only picked up by a “Refresh Metadata”. Rescanning the library does not.
Maybe so, but unless you know that, then you don’t know that. I’ve used Plex for many years, and this is the first time I’ve ever hit this problem.
Indeed, I have lots of Extras/Featurettes on existing tv series and existing films, and I’ve never done a “Refresh Metadata” before for this sort of scenario. I suspect, if the files in question happen to be in the right place/format from the outset then they appear.
Yeh, I went through that article a number of times, and if it had simply mentioned somewhere that “Refrehs Metadata” is what can absorb/update the structure in Plex, it would have saved me a lot of time/hassle
@NeilF , thank you the Refresh Metadata is was resolved my new addition of Featurettes to my show. Thank you again for that and old that 1) Scan library adds the new episodes but not the Featurettes (or it does, but additional step also needed to update the show completely). 2) Hit Refresh Metadata to see new additional Extras added to the show.
