Gravity Forms Redirect not working after form submit

The gravity form loads. Yay.

The confirmation text loads when the popup is set to Refresh or do nothing (Ajax Forms).

But nothing happens/no redirect happens when this setting is on the other two options

I tried the gravity form with ajax set to true as well as false:

[gravityform id="2" name="Newsletter SignUp" title="false" description="false" ajax="true"]

I've tried the gravity set to redirect to a URL as well as to a page.

Is this supposed to work? Known issue / known fix?

Lemme know - this is on a deadline and loading a confirmation message is better than nothing... but I want the options to do a redirect to a thank you page when that's what we want to do.
