Last Saturday I purchased a new iPhone and downgraded my old one to be simply the controller of my Audirvana+ music server (and iRobots too…)
Then I set up a new iCloud account and added it to my “Family Sharing” group: me, my wife and this new account.
The problem is that I can share any other Apps I purchased in the past, but not Audirvana Remote.
It seems that I have to buy it again. Not a big problem, it’s cheap, but the specifications read that it should support Family Sharing…
