If your embedded form is not updating on your website, you may need to clear your browser cache.
All web browsers cache information about the website. If your form isn't updating properly after you've changed it in Upsales, browser caching might be the issue.
To clear the cache of your browser use Cmd+Shift+R (Ctrl+Shift+R on Windows).
If you've copied your form from using the "Code for custom styling" tab, the content won't update with the changes you make in Upsales anymore. You'll still get the submit when the form is filled out, but the form won't update itself with things like new fields, or new field names.
The solution is either to publish the form using the Link address-option or the Embed on website option, or to simply copy the form from the Code for custom styling-tab again (after you've made form changes) and paste it on your website.
