UPDATE: After providing a workaround that involved clearing the YouTube Music cache, TeamYouTube finally provided an update last night which confirmed that the issue is now fully resolved.
The original story continues below.
YouTube Music is experiencing a partial outage affecting the homepage and loading of playlists and library for many listeners. The issue was discovered around 1:50 PM PST today and is occurring on all devices including the web.
The issue was tweeted by the official YouTube team account after reports of the outage started pouring in. When opening the app, the Library and Explorer tabs appear empty, as if nothing was ever added to them.
