Can’t log in with fb – Spotify Kids Review

So we are a premium family account who is logged in with Facebook. Can’t log into this app because there’s no Facebook option. Unable to review. Hope this can get fixed. Also I don’t want to change all of my Spotify set up/log in just to be able to log into this. Develop it to where we can use our fb or link from our premium account. Thanks!
