I pay for Premium Duo. I have premium service but my partner does not.

My partner is named on the Duo plan but she still gets averts and invitations to upgrade to premium.

Hey @Bluegraham870,

Thanks for reaching out.

In that case, they most likely didn't log into the account they accepted the invite with, but a different one. I recommend asking them to log into https://spotify.com/account to check if the account they're logging in with is part of the Premium Duo plan.

Let me know how it goes 🙂
