I think the choice of the artist name is important to avoir this issue but in every case after some submission of releases the musical platforms know you and this will not happen no more
I tag the iMusician support @Fabiola to give you more info about this issue
@A2D:
Thank you for your Feedback.
Of course I entered the correct artist , but since it is obligatory to also insert the composer, I entered my real name for the composer as well. And since there is a Spotify account with my real name (but not me) this issue seems to happen.
So I hope that imusician staff can delete the wrong artist “Robin Berger” and I would like to know how / if I can avoid this to happen in the future…?
