Yes, it seems to be all sorted. I deleted the original with Distrokid and then immediately uploaded the amended version.
For a while, when I searched on Spotify, there wer two versions and the version on my "popular" tracks and in playlists was still the flawed one. But I've just checked again and it seems that only the good version is out there now.
I have this same question. I want to keep everything about the release the same except for the record label name because we changed the name of our label and want that name to be reflected on all of our past releases for branding purposes. Does anyone know if this is possible and if so how? Thank you in advance.
