iOS app to reproduce issue

Attached is a simplified test case that reproduces the issue.  

 - Compile and run the iOS app
 - Touch the first login button
 - Touch the second login button

After the blue page appears you will get a NRE.

I found that a null check on the following line avoids the issue, but feel the real fix is more complicated than that.

Hence closing this issue.
