How did some random join my blend?

[#1]

I created a blend with my boyfriend and sent him the invite. It was only us two until later that evening someone else joined. Neither of us had sent any other invites, nor recognized the account. Aren't the blends private? I mean you would think since there is an invitation system

Hi there,

Thank you for taking the time to post in the Community.

This seems odd as you need an invite to be able to join a blend playlist.

Do you mind creating a new one to see if it happens again?

Let us know how it goes so that we can continue to assist you if you need us to 🙂

Have a great continued weekend!
