I think I have found a potential bug with Webflow forms…
Validation messages aren’t working for me on checkbox fields on any of my sites in Webflow.
They work perfectly in the preview of the site. But on the live version the error message doesn’t show for required checkboxes that haven’t been checked.
One example can be seen on the form at the bottom of the following page but I have the same issue on other pages and other websites: https://www.everound.com/
Here is my site Read-Only: Webflow - Everound
