Hey @art1719,

I looked into your app and it appears you do not have the **Development** Redirect URL in your Whitelist, so the Development (Test) install will throw the redirect url error.

I tried installing your Production app, on the Submit page, and it worked because you had the Production Redirect URL as your Whitelist.

Let me know if that helps! 🙂

Thanks,
