If you are able to successfully create embedded wallets for your users and receive the following error:

[JWTInvalid: Failed to base64url decode the payload]

• First double-check that you are have followed the steps in the quickstart guide.
• If you continue to run into this error, ensure that the react-native package in your application is up-to-date.
• Finally, you can override the atob method necessary for JWT decoding with the following polyfill:

// Add this to your polyfills file or entrypoint.js
const _atob = atob;
atob = (val) => {
  try {
    _atob(val);
  } catch {
    _atob(val + '=');
  }
};
