A friend and I are getting this message on our iPads via the Vodacom 3G Recharge Application for iOS:
Error while saving object. could not insert: [com.vodacom.ipad.server.entity.ProfileUsage]
We had tried removing the App and reinstalling it, switched the iPads off and on again, removed the sim card and reinstalled them. No resolution.
Please investigate, as we can only check via a web browser now what our balances are, etc.
