Ahhh sorry, I didn’t get that. Now I saw what you mean and also I understand what the problem is in your case. Like I said, notify seems to have a problem processing SC links but YT links normally work. However, after posting the track, you have to wait a bit. Did you ever notice that your tracks do not appear on the soundtrack page for a while after posting them? After a while they do and then they are ready for the notify player. Check the site of Kimetsu no Yaiba again, you will see that it’s working now :)
