Sprout Form redirect after submit not working correctly

Question

All my forms on sprout form won't use the redirect they get assigned via the Form builder. Whenever a form is succesfully submited it redirects to my homepage instead of my thank-you page.

<form class="form__regular" method="post" accept-charset="UTF-8" id="contact-form">
    {{ getCsrfInput() }}

    <input type="hidden" name="action" value="sprout-forms/entries/save-entry">
    <input type="hidden" name="handle" value="{{ form.handle }}">
    <input type="hidden" name="redirect" value="{{ form.redirectUri }}">
</form>

Even if I write the redirect URL manually it keeps redirecting me to the homepage.

The only way I can get the redirect to work is when I let sprout forms render the fields.

In Craft 3, Form redirect values must use the hash filter:

<input type="hidden" name="redirect" value="{{ form.redirectUri|hash }}">

It's mentioned in passing in the docs here.

Without that hash filter, you'll get redirected to the home page as you are experiencing.
