Restore the full discography to artist pages on mobile. As of a recent update, artist pages no longer seem to include this. The only way to browse an artist's albums or singles is to search for the artist and tap "see all albums" at the bottom. This shows all albums with the search string in the artist name or in the album name, in no discernable order.
When I want to hear more of an artist's music, I would like to be able to view their records in a logical order (i.e. chronological). This also makes it much easier to find a song that I don't know the name of but I know the artist.
