Norton Identity Safe on iOS 7 crashes when trying to unlock vault. A fix on the way and when?

Using iOS 7 on iPhone 5.  I can logon to my norton account fine, but trying to open the safe with my password causes the program to close without error message.  I have submitted a couple of crash details via the app (it prompts when opening again).

 

Can someone confirm Norton are aware of the issue, and perhaps provide an eta for the fix?
