Before Apple Music, there was iTunes Match. The service uploads your music library from the Music app on your Mac or iTunes for Windows on your PC. Then you can access your music library on all of your devices that have Sync Library turned on.
The problem is, although many people migrated to Apple Music, which can do the same, other users preferred to pay $24.99 a year to remain uploading their own music library with iCloud, but now users are reporting an array of problems with iTunes Match.
As seen in several Apple Support Forums and Reddit (via MacRumors), users have reported that the service has practically stopped working.
