Tested with all versions of react-native-lock@1.29.x and I also face the same issue... (happens not only with Google but also with all social connectors I've tried -- Facebook, Instagram, etc.)

For me, this bug happens always when I have useBrowser option enabled. The registration seems to work correctly in the background as the account is successfully created on the server-side, however the user auth token is not returned back to the controller, instead the UI is stuck at the blank screen.

(Might be somewhat related to #131, #92)

@pilwon does it work sometimes for you? Mine works 70-80% of time

[pilwon]

@chitezh It doesn't work for me at all anymore. No issue with {useBrowser: false}.

[chitezh]

Thanks. I'm trying to establish if it's the same issue
@pilwon don't you get the userAgent warning when you use {useBrowser: false}

I've also started having a problem. The only thing I've changed from what I can tell is I've added redux into the mix. Anybody else also using Redux? #92 Gave me the impression that it could be redux-related but not sure yet. I'm going to try dismantling redux and see if that gets me anywhere.

It's working now. I don't know if this is a redux issue still because I may have just messed with enough code to force a harder reload than what I was doing before.

My current theory is that this may be a hot reload issue. Because I noticed that everything seems to work when the app is hard-reloaded and the Lock login screens shows with a slide-up animation. I was not seeing that same animation when it was hot reloading and wasn't working. Hope that helps.

Tried again this morning and I'm still getting the white screen after login.
