If you submit a release with multiple main artists, the release will be placed on the artist page of all these artists on, for example, Spotify. But beware: this only applies to releases with 1 to 3 artists.
Does your release have more than 3 main artists? Then most stores will place them under ‘various artists’, and the release will only be visible on artist pages under ‘appears on’.
Unfortunately, this is a limitation of the stores that we cannot influence as a distributor.
If you want to avoid this, you can choose to add extra artists after 3 main artists as ‘featuring’ artist. This prevents the release from being placed under ‘various artists’.
