Some users are currently not able to open the link to My Forever Favorites playlists - the app freezes or the playlist loads indefinitely. If you're experiencing this, try the following troubleshooting steps:
Make sure that you have a strong WiFi connection
Restart your router, the app and your device
You can also try to access your own playlist by typing spotify:forever-favorites in the search bar on mobile to navigate to it.
