I deleted my app on iPad, and tried to download it again. BUt I saw.. It is iPHONE ONLY...
this might be the problem.....
I don't think problem should be between different versions, versions have nothing to do with bitcoin.
As you said wallet generated new public address, that's not problem at all. Mutli HD wallet is meant to generate new addresses periodically. To check all addresses associated with your account, click 'sign message'.
But if your wallet is empty then this could be a concern. Check whether your transaction is confirmed or not. Also if you double spent it or not.
