I recently had to restore my iPhone as per recommendation of the Genius Bar.
My iPhone is restored using icloud backup.
NEM wallet app seems to be working correctly.(I can see the balance of accounts)
Then I made new wallet in iOS app, and I send 100k NEM to that new wallet from exchange account.
I can see 100K NEM in new wallet, however i got a error message “Failure. Signature is not verifiable” when I tried to withdraw from new account.
In addition to that, the app crashes when I tried to export private key of this new account.
(Don’t need to care about other old account because I have .wlt file that contains other old account’s private keys)
What should I do to help my 100k NEM?
