Family Sharing - can I approve a Mac app from my iPhone
We have Family Sharing set already for all our iCloud accounts which we have been using on our various iOS devices.
I have just bought a Macbook Air for my daughter, and we tried requesting Family Sharing approval for a Mac OS X App. The notification appeared on my iPhone X, but when I click on it, the approval screen appears but just with the blue Cancel button on top left, and "LOADING" in the middle, the Get button that should be on the top right never appears even after several minutes.
Is this supposed to work? I didn't find any references anywhere to approving a Mac app from an iOS device. Thanks.
MacBook Air, macOS High Sierra (10.13.3)
