React-native-auth0: Android: Unable to enter email code when resuming application from launcher

[seanpatrickcatlin]

Issue

When using react-native-auth0 on Android to authenticate against an auth0 client using a passwordless email code a user is unable to enter their email code when resuming the application from the launcher or launching it from a home screen shortcut.

Steps to reproduce

1. Download the auth0 sample app from https://auth0.com/docs/quickstart/native/react-native (my sample app was in a file named 00-login.zip)
2. Open a terminal window and cd to the 00-login.zip location
3. unzip 00-login
4. cd 00-login
5. npm install
6. react-native run-android
7. Click on the "Log In" button
8. Enter email address and press "submit"
9. Notice that auth0 lock is now requesting a code
10. Press the Android HOME button
11. Open email application on device to get the code
12. Press the Android HOME button
13. Open the application launcher
14. Tap on the Auth0Sample app

Expected Behavior

I am shown the Enter a code custom tab

Actual Behavior

I am shown the original page with the Log In button

Thanks for the gif, please can you retest in a real browser such as Chrome or Firefox.

Thanks for all the details 🎉 . Does this still happens if you open the app from the "recents apps" instead of clicking the app icon in the drawer?

• Testing with Chrome, Firefox, and Firefox Focus all show the same behavior on multiple devices, I will attach some gifs to this post shortly

RE: Does this still happens if you open the app from the "recents apps" instead of clicking the app icon in the drawer?

• This does not happen when resuming the application from the "recent apps".
• This does happen when:
  
  
  
  1. Tapping the app icon from the "Android Launcher" / app drawer
  
  
  2. Tapping the app icon from a shortcut added to the "home screen"

I can confirm that this happens just as described above. Though it was not introduced in the latest PR https://github.com/auth0/react-native-auth0/pull/126 so this requires a bit more research on our side.

@seanpatrickcatlin if this is still happening, can you please confirm if you are or not using react native navigation library along with this one?

I will check if this still happens within the next day or 2.

This bug report specifically references that this happens with the sample project provided by auth0, so react native navigation was not used.
