Oops, Exportify has encountered a rate limiting error while using the Spotify API. This might be because of the number of users currently exporting playlists, or perhaps because you have too many playlists to export all at once. Try creating your own Spotify application. If that doesn't work, please add a comment to this issue where possible resolutions are being discussed.

It should still be possible to export individual playlists, particularly when using your own Spotify application.
