App for IOS 7.2.1

Hi I have owncloud on my old iphone 4s. When I bought the app it gave me the option of downloading an older version of the app, becouse we only have IOS 7.2. We have family share anabled, but I am unable to download the app for my wife's iphone, it will not give the the option of an older version.

Resolved I was able to transfer it
