Unless there is a bug or something, I just noticed that forms are no longer submitting unless the site is hosted with WF.
This is the last thing I remember about forms hosted outside of WF https://forum.webflow.com/t/question-about-forms-and-hosting/29094
But as I was digging into why forms were broken on several sites, I found this https://forum.webflow.com/t/forms-without-hosting-at-webflow/36304
So it looks like what I'm seeing is correct. If so, was there any kind of advanced notification of that feature change? If there was, I don't remember it but I may have just missed it. Maybe one of these guys can let me know? @callmevlad @PixelGeek
