Changes in the designer are not displayed in the preview

Hello! Changes in the designer are not displayed in the preview. And on the site too.

Looks like this was caused by a form cache. We have cleared the form caches and it looks good now.

I cleaned my browser cache and cache in jotform settings. It doesn't help. I think the mistake is on your side. It is noticed that the data was updated after 2 hours. This is a very long time.

 When I click save, nothing happens. The wheel is spinning and spinning ...

I tested your form and I was not able to replicate the issue you mentioned, please see screencast below.

Could you please try again and see if the issue persists on your end? If the issue persists, please try with another browser (I'm using google chrome).

The preview problem remained. Cleaning the cache does not bring results. Please see the gif file. After editing in an advanced design, changes are saved only for the designer. Preview opens the previous version. I hope you will be able to correct the error.

Thank you for your detailed screencast. In fact, there is a little conflict between some CSS codes. When you change the form title color via Advanced CSS Editor, the CSS code is writing into form CSS page as below:

But there is another CSS code(is our default) in the form that affects the title color. 

We must give a priority to the CSS codes we want.

Your code should work.
You do not have to do that for all CSS codes. This is about the reading order of the HTML page. The first written codes are being active.
Please contact us if you encounter any other issues.
