Auth0 callback fails randomly in iOS

Hi,

Our React Native Expo app is using Auth0.com and authentication works well in Android, and in most of the iOS devices. However, some iOS devices authentication stops with both Facebook and Google login to attached screen.

To make things confusing, problematic devices range from old iPad2 to iPhone7 and different iOS versions. For other users same phone model and SW version works ok.

In the code, redirect_url is sent to Auth0 and even in failing cases it seems to be correct one. But after process stops in that Safari screen, it never returns to our code.

Would appreciate a lot if you have any advice or even wild ideas what to do?

Thanks!

Well, eventually had to find an alternative solution: Using Expo.io social login and new Graphcool schema extention functions.

Without Auth0:

I’m facing the same issue. The problem can be reproduced if I clear Safari’s cache and then try to login.

Wondering if anybody has a clue on this one.
