This hasn’t been filed as a feature request because it has long been recognized as a bug. I tried to find the original reports of the problems surrounding refreshing libraries after metadata tags are updated, but there are so many that I found it too hard to sift through them all.
This problem has existed for so long, and has been so widely reported, that the workaround for it has acquired a name, “The Plex Dance.” I personally think an issue that has been so prevalent for so long should be highly embarrassing to Plex, but they don’t seem to care too much about it.
