In Plex Web, when I view the page for an artist with multiple albums, the albums are displayed in reverse order of their release date, or so it seems. There is no way to modify this.
In the current design, the intuitive expectation is that the albums should be sorted according to the "Sort Album" entry in the Edit Album popup.
The preferred behavior, in my opinion, is that the user be able to select the sort order, in the same way the user selects the sort order in the Library/By Album view.
The option is global at this point and I don't think there's a list of all valid choices, but I can say for certain that year:asc works to get albums ordered chronologically. I will never understand why the default was made backwards from this.
