Ella's relation with her mother

Lorde made favorite daugher, and i dont know if she assumes a persona of someone with mommy issues, but dont make sense for me that her mother in instagram made so much noise with the album and show so much love for her daugher before and after the release, like, eidnt she listened to that song?? or does she listened an knew it wasn't about her? I know is something very personal but this dont enter in my mind.
