Following the recent changes to the mobile app, I can no longer view the playlists and subfolders I keep arranged in folders/subfolders by the custom order I have used for years for those playlists/subfolders. When I filter for playlists and select custom order, only the top layer of folders follows my custom order - not the subfolders or playlists therein (or further subfolders within subfolders etc.). Please extend the custom order option under playlists in the new library setup to include the order of playlists within folders, subfolders within folders, playlists within subfolders, etc. I have hundreds of playlists saved in folders/subfolders all very particularly and deliberately arranged, so I can easily locate what I want to listen to. Organizing these subfolders/playlists in the methods now available on the mobile app (recently played, recently added, alphabetical, creator) makes little to no sense and adds minutes to the time it takes me to find a particular playlist (as I will now have to scroll through tens to hundreds of playlists in a nonsensical order). This is extremely frustrating, especially since the custom order of my entire library of subfolders and playlists is still available on the desktop app and webplayer - just not in the mobile app (which I use almost exclusively). The only workaround I can think of on my end as a user would be renaming literally thousands of playlists and subfolders (by adding 000, 001, etc., to the front) so that they will display in the proper/intended order alphabetically. Surely there must be a way to still enable us to view our folders, subfolders and playlists in the same way we've kept them organized for years on the mobile app. Thank you.
