No "Available Apps" on Family Share Apple Watch
I see a lot of forum and support posts for Apple Watch customers with issues that say to go to the watch app on an iphone and go to the "available apps" section. I don't see that section for my child's apple watch which was setup under a Family Share. How do I access this option? There are some apps (namely Spotify) that do work on a cellular Apple Watch w/o a phone present. I don't see why this situation shouldn't apply and allow me to install Spotify on my child's watch?
