I'm sure this might be an idea/or solution somewhere, but I haven't found it in my searching.
I have a Family account that includes my daughter, who does not have any social sharing accounts (i.e. facebook, twitter). She used to use my account, until the Family account option, and so I have a lot of Playlists which really are hers.
How can I share these playlists with her? I tried sharing, but when I type in her username, it says no results found, and no option to proceed. The Guide on sharing says that I should be able to share by entering her username, but as I explained above, it doesn't work.
I tried this from both the Windows desktop app and my Android app. Same results.
Thanks for the idea.
As mentioned in comments, this is already possible.
