In the past, I guess it has been a few years now, whatever I added was always at the top of the screen and easy for other members of the house to see. Now it is a static/alphabetic of my categories. With dozens of categories it is not so easy to tell when I add something new. Is there a way to change this back so that the category that has the newest content is at the top?
go to Settings - Server - Manage - Libraries. In there, expand one movies-type library and Reset Customizations. Repeat with at least one tv shows-type library.
While you are there, make sure the checkbox āMerge Recently Added itemsā at the bottom is ticked.
reset the web app under Settings - Plex Web - āShow Advancedā - Debug - āRestore Defaultsā
Or inspect them yourself. Take a look at the Plex Media Server.log file and seek for messages about database corrupt or malformed.
If you find these, you may have to repair your database.
