We cannot submit a release to streaming services if any part of the release has an error, even if it's just one file that has an issue. This is because we cannot delete/edit the tracks on a release once it is uploaded, and the error'd track is still associated with the release.
You'll need to abort the upload and re-upload a corrected version of the album, ensuring that your artwork and audio files meet all requirements.
Please see here for some specific information about uploading via iOS:
