Cookies lost after WordPress redirect
Anyway, I built a form and called a function in the plugin to set the cookie when the form was submitted and redirected to the page. Through testing, I can see that the cookie is indeed set when the form is submitted, but when the redirect occurs, I lose the cookie and the value associated with it. I've been crawling forums and trying to debug this for a long time and I think I'm missing something super simple. I've tried wp_redirect, wp_safe_redirect, header Location:, window.open(), etc. p>
If I use wp_die($_COOKIE) before the redirect happens, I can see my cookie, so I'm sure it happens after the page redirects to some other page.
How can I submit a form, set a cookie, and redirect (to a different page on the same site) without deleting the cookie so that I can use the data on the redirected page? < /p>

If it helps, here are the form actions:
<form action="' . esc_url(admin_url('admin-post.php')) . '" method="post" id="configurator">
