Form Data Not Submitting (Test Site)

I am just about ready to publish the site I’ve been building to my domain (currently only on my test URL). I cannot get my forms to submit data - newsletter sign up and contact us. I’m pretty certain I have everything configured properly and have tried as many different things as I can to get it to submit. WTH am I doing wrong? Only thing I can think of at this point is that the forms won’t work until I use the actual domain name with the site - which I don’t want to do because this is not a new website.

Here is my site Read-Only: Webflow - CIO Mastermind Website
