expo-auth-session for Instagram auth doesn’t work if

  • I haven’t previously logged in Safari
    and
  • I have Instagram app installed on my physical device.

If these two conditions are true, I can finish the auth flow, then I am redirected back to my app as usual, but auth modal is still the same and I don’t get any result.
If I delete Instagram app on my physical device, then it works fine.

I doubt that when the auth flow starts, for a short moment, I am redirected to Instagram app before being redirected to the auth route. The problem might be somewhere here.

const apiBaseURL = 'https://api.instagram.com/oauth';

//TODO: Replace appId with yours
const appId = '99999999999';

export const isAuthSessionUseProxy = () =>
  Constants.appOwnership === AppOwnership.Expo;

export const getAuthSessionRedirectUrl = () =>
  AuthSession.makeRedirectUri({ useProxy: isAuthSessionUseProxy() });

export const fetchIGCode = async () => {
  WebBrowser.maybeCompleteAuthSession();

  const redirectUrl = getAuthSessionRedirectUrl();

  const discovery = {
    authorizationEndpoint: `${apiBaseURL}/authorize`,
    tokenEndpoint: `${apiBaseURL}/token`,
  };

  const request = await AuthSession.loadAsync(
    {
      clientId: appId,
      redirectUri: redirectUrl,
      scopes: ['user_profile', 'user_media'],
      responseType: AuthSession.ResponseType.Code,
    },
    discovery
  );
  const result = await request.promptAsync(discovery, {
    useProxy: isAuthSessionUseProxy(),
  });
  return result;
};
