I have a medical app for iPhone (DrugDoses) that contains a medical database (2200 entries). As this database is frequently updated, the subscription to the database is only valid for two years. I would like the user to be able to renew his subscription a few days before the end of that 2-year period, using an In-App purchase. The programming has already been done, but there is a bug found by the iTunes review team that we cannot seem to fix. We need someone to be able to find out where the bug is, and to be able to fix it.
