## Known Issues with `fetch` and cookie based authentication

If you've gotten here by reading linearly through the tutorial, then you are a pretty impressive human being. Congratulations. Next, you might want to check out [all the cool stuff the community does with React Native](more-resources.md).
The following options are currently not working with `fetch`
- `redirect:manual`
- `credentials:omit`

* Having same name headers on Android will result in only the latest one being present. A temporary solution can be found here: https://github.com/facebook/react-native/issues/18837#issuecomment-398779994.
* Cookie based authentication is currently unstable. You can view some of the issues raised here: https://github.com/facebook/react-native/issues/23185
* As a minimum on iOS, when redirected through a `302`, if a `Set-Cookie` header is present, the cookie is not set properly. Since the redirect cannot be handled manually this might cause a scenario where infinite requests occur if the redirect is the result of an expired session.
