Hello, thank you for any help you can throw my way, this problem has absorbed my life for 2 weeks now.
Long story short, ever since Android Version 10 I cannot sync my Pixel 2 XL correctly. I have tried iTunes, MediaMonkey, and now MusicBee and there is always some sort of completely crazy problem with no apparent solution.
I have finally gotten to the point where if I sync (usually twice for some reason) to MusicBee I will get my entire library (2018 songs). There will be about 30 random songs that don't sync correctly, they will have no artist and have a name like "1 songname songartist" or "# songname songartist" but no amount of tinkering has fixed this, even going as far as downloading a different file of the song.
What is even more perplexing is the playlists, which will do a number of different things every time I sync them. Sometimes they won't show up at all. Sometimes some will. Sometimes they will all be blank. Other times some will be blank. But most of the time, after an afternoon of trying, I will finally get all of the playlists on and accurate, only to unplug my phone, go to sleep, and wake up to them all blank the next morning. I have heard of this happening on other devices from scouring these forums, but no fix I try seems to work.
I have tried every type of playlist file, putting the playlists on the home directory and then moving them into the playlist folder, clicking "create a sub-folder for each playlist and its tracks", clicking "use relative file paths" and a number of other voodoo ritual ideas that went nowhere like manually typing "#EXTM3U" at the start of the M3U file. I have also tried syncing less playlists, restarting the phone, reinstalling the app, and trying different apps (I put my entire library manually into MediaMonkey, no help).
At this point I am just completely exhausted and frustrated that I cannot listen to my playlists, so any and all completely crazy solutions thrown my way would be greatly appreciated.
