NXOAuth2Store Configuration lost after app restart

[tekatool]

My app creates an account successfully after OAuth2 flow.
When I stop the app and restart, it fails when I try to use NXOAuth2Request SignedURLRequest.
Looks like the config info is not persisted ?

I am using iOS 8 in simulator.

Including the trace below...Any prompt help is really appreciated...

terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'No token or no authorize URL'

The only thing that is persistent are the access tokens (in the keychain). You need to make the calls to NXAccountStore each time the app starts before anything. I recommend doing that in +initialize of your app delegate.
