App works until you update or restore

I have had this app for over a year and it works great... until you update iOS or you need to restore to a previous backup (bought new tablet and phone).
Then, after putting in the new devices with Apple assisited restore... it loses itself. Nothing gets restored (password protection in iTunes is requred for it to save that stuff). It loses everything and I have to "re-register" for everything and remove the Authenticator and re-add it for other accounts.

No, Im tired of this junk. Even Battle.nets Authenticator isnt this inept!

Wappaloo about Google Authenticator, v3.0.0
