Windows Devices and Apple Music fail to sync music to iphone

There's a plethora of problems with both of these apps that I've seen since switching from iTunes. I'm wondering if anyone has workarounds/a place to report them.

Apple music:

• Lacks the ability to consolidate your media library. It's available on the mac version and iTunes (file->library->organize library->consolidate files) but it's not available on Windows Apple Music.
  • This appears to cause lag when loading playlists
• Lacks the ability to switch output devices (i.e. when connecting a bluetooth device), iTunes appears to have been able to do this.

Apple Devices:

• When syncing music, it often disconnects from Apple Music, even when the app is open
  • Reproduce:
    • Open Apple Devices
    • Plug in an iPhone
    • Open the "music" tab (You'll see a prompt saying to "open apple music")
    • Open Apple Music
    • Return to Apple Devices (the prompt hasn't disappeared)
  • Reproduce (alternative):
    • Open Apple Music
    • Open Apple Devices
    • Plug in an iphone
    • Close Apple Devices
    • Open Apple Devices
• When syncing music, For playlists with folders, it fails to recognize playlist folders, art, or previously checked items
  • Reproduce steps:
    • Open Apple Music (wait for it to load)
    • Create a playlist folder (Named "Bar")
    • Create a playlist inside of that folder (Named "foo")
    • Open Apple Devices
    • Plug in an iPhone
    • Open the "music" tab and select "Sync music into <your phone name>"
    • Select "Playlists" from the sync tab menu
  • Expected results:
    • Playlist folder structure matches Apple music with "Bar" being a folder holding "foo"
  • Actual result:
    • "foo" will be present on the top level with "bar" completely non-existent.
• When adding playlists, new playlists don't show up in Apple devices while Apple music is open. Keeping both apps open seems to be the intended use-case as Apple Devices doesn't show the music tab without Apple Music being open.
  • Reproduce:
    • Open Apple music (wait for it to load playlists)
    • Open Apple Devices
    • Plug in an iPhone set up with syncing enabled for a playlist
    • Create a playlist on Apple music
    • Return to Apple Devices
    • Go to music->"playlists" for the iphone
  • Expected Result:
    • New playlist is present in Apple Devices as a sync option
  • Actual Result:
    • New playlist is not present in Apple Devices
• When Syncing music, previously checked off playlists become unchecked
  • Reproduce:
    • Open Apple music (wait for it to load playlists)
    • Create a playlist "foo" and place it in folder "bar"
    • Open Apple Devices (we do this afterwards because it doesn't update)
    • Add "foo" as a playlist to sync by "checking" it
    • Sync with the phone.
    • Unplug the phone after ejecting
    • Close both Apple Music and Apple Devices
    • Open Apple music (wait for it to load playlists)
    • Open Apple Devices
    • Plug in iPhone
    • Navigate to Music->Playlists
  • Expected result:
    • All playlists previously marked for syncing are checked
  • Actual result:
    • All playists that were synced in the past appear to be randomly checked or unchecked
• When Syncing iphone, selecting "skip backup" doesn't close the keypad on the iphone
  • Reproduce:
    • Open Apple Devices
    • Plug in an iPhone
    • Select "sync"
    • During the backup phase, select "skip backup"
  • Expected result:
    • Backup step is skipped, or user is prompted to close the keypad on their iphone
  • Actual result:
    • Button "clicks" but otherwise does nothing. iPhone keypad's button still says "cancel" implying that the sync is going to be cancelled.

Any help is appreciated, I could understand itunes taking forever to load because at least that eventually worked, being unable to use my playlists is a bit insane though.
