I have an app in the appstore that used to be paid and with no ads.
I want to upload an update, make the app 'free', add ad's, that could be removed by purchasing "No ads 'in-app purchase'".
I don't want users that have paid for the app before to update the app and see ads.
I want to grant "No ads 'in-app purchase'" for users who is updating the app.
Basically, if a person is updating, then no ads is 'purchased' by default. If a person in downloading the app for the first time, he gets ads.
Is this possible? Any workarounds?
