Question If i update the application with a new datamodel, will the iOS application be responsible for converting the old books into a new version of the data model? Say, will the iPhone or iPad have to convert them? How will I motivate

问题 This issue has had me going for days. I have a simple app, that displays banners and interstitial adverts.

When the user opens the ios app and logs into his account, he would stil have the item since its saved on the server. This would also be done in reverse. Does the android or ios policy allow this
