Submit new Song - Spotify Search does not work

Hi,
trying to submit a new song.
I typed Sixturnsnine in to the search field but it does not find anything. Typing other artists that exist on Spotify produces the same failure. Alternatively I pasted the Spotify track URL

https://open.spotify.com/intl-de/track/7HZqKqxwUItJhJrU8tMDBW?si=f219476334844f44

of the track I want to add. Same error.
Pleas assist.
