User Profile

We are currently forcing our users to use always the last version of our app available on the store, in order to handle breaking changes in the server.We show an alert at app launch every time a new version is found on the app store and we bring the user to the app page on the store. It is working correctly, but we noticed that often the app store does not show the "update" button but the "open" one instead.At the moment the process is very confusing because when the users press "open" it goes back to the app but then the alert redirects them to the app store again to update the app.This looks like a bug, there are similar questions in this topic from last year, but similar issues has been recently reported on stackoverflow too http://stackoverflow.com/questions/37065424/itunesstore-not-showing-update-button-for-appWas this already reported and fixed? Is it a regression? Did you receive any other report about this in the last months?Are there any plan on your side to work on this issue?If this is not going to be fixed soon what could we do to improve our users experience?Which is the best way to help the user to move to the new versions and being sure they will be able to update the app when prompted?Thanks
