Description of Issue

Date Added sort stopped updating two days ago, rebooting Roon didn’t help. Happened a week ago, rebooting Roon did help for a few days.

Problem was a misunderstanding. I had broken up a large classical album into its components (the Boulez Sony box), and was processing each, adding the single album covers, changing track numbers, etc., and when I added these back to the appropriate folders, they didn’t show up in Albums Added and Date Added sorts. I had assumed that because I had deleted the box from the Roon folder, that when I added back each single album, it would register as a new entry. Obviously didn’t, a reasonable database programming option.
