I see a few people have asked this question already, but I don’t see a clear solution in those other threads.
I’ve embedded a form on our WordPress site, and added a redirect for when someone completes the form. However, it doesn’t work. It looks like it activates the pop-up blocker on my laptop (which is a default setting on a MacBook Pro I just purchased, so I’m assuming others will have that, too). It reverts back to the form instead of sending people who completed it to my thank-you page.
