How do I identify the premium for family owner?

[Mrsbridgewater]

I know I set it up on my email account - but when I log in I get a message saying:
"Spotify Premium

Your account is part of a family plan, please refer to the Premium for Family owner to manage your plan."

So what's going on?  I want to add a couple of my children to the account but can't 😞

Having the exact same issue. I am the owner and PAY THE BILL every month. Why does it tell me to refer to the owner of the account?
