If Apple Music AutoMix Not Working, start by checking that your Apple Music app and device are updated to the latest software version. Make sure AutoMix is enabled in the playback settings and that you are using a supported device and subscription. You can also try restarting the app, checking your internet connection, or downloading the songs again if playback is inconsistent. Some tracks, albums, and music types may not support AutoMix transitions, so testing a different playlist can help identify the issue.
