Slow submission with WP-Forms pop-up

Greetings,

I created a pop-up with https://wppopupmaker.com/ that requests a user’s email address, but the time for the form submission process to complete is sometimes over 4 seconds. Curious what I can do to speed up the process…

I see there is a React error in the console coming from the theme, but I’m not sure if this is related.

I would appreciate any advice/assistance.

Thanks,

Paul
