Question: None of my past purchases for items in the App Store are listed.
The message is "you have not yet purchased any apps."
If I search for an app like Pilexmator which I purchased, It shows open as it is installed. I just downloaded the Kindle App on My Mac which I purchased long ago and it showed "Get".
