## Issue

I have not reproduced the issue on dev/qa environments. Everything that I know from end-user report, app runs webflow and fails immediately after the successful login on the server that

Looks like duplicate to https://github.com/FormidableLabs/react-native-app-auth/issues/388

Those errors started after RN upgrade to `0.62.1`. Before that app used `0.59.x` and no bugsnag reports are detected

## Environment

* **Your Identity Provider**: Custom InHouse OAuth Provider powered by Doorkeeper (https://github.com/doorkeeper-gem/doorkeeper)
* **Platform that you're experiencing the issue on**: iOS (I have not tried on Android)
* **Are you using Expo?**: No

```
"react-native": "0.62.1",
"react-native-app-auth": "5.1.2",
```

Beginne mit App/Login.tsx in Zeile 76 und dem react-native-app-auth-Aufrufpfad in node_modules/react-native-app-auth/index.js:187; vergleiche den iOS-Fehler mit Issue #388 unter Verwendung von React Native 0.62.1 und react-native-app-auth 5.1.2. Als abgeschlossen gilt die Reproduktion des Fehlers nach dem Login oder die Dokumentation, warum er nicht reproduziert werden kann und ob dieses Issue ein Duplikat ist.
