I see, that’s good to know, thanks! I just thought it started over again (which could be what you want if someone illegally registered your tracks, and now you have control).
Yeah, it’s a bit of a mystery then. Some tracks of mine are “difficult”, meaning they sometimes don’t trigger claims when I test myself. Other tracks always trigger claims right away, even if it’s a new YouTube channel with 0 subscribers and 0 views. I have not been able to recognize a pattern yet.
