Hi @greggs
Welcome to the Auth0 Community, it’s great to have you on board.
You could create a post login Action to do the redirect as per this document https://auth0.com/docs/customize/actions/flows-and-triggers/login-flow/redirect-with-actions#start-a-redirect
So for you it might look like this
exports.onExecutePostLogin = async (event, api) => {
api.redirect.sendUserTo("http://localhost:3000/app");
};
Does this work for you?
Warm regards.
