Hi, I believe the shortcode got formatted inside HTML <code> tag. Please remove the existing shortcode and paste it as plain text in the visual editor. Alternatively, you can paste it in “text” mode which will automatically remove any existing formatting.
I went ahead and started over and then the button worked.
When I try to add things like force download, change the color, etc. that is when the link stops working!
Your HTML code still looks formatted (inside a
<pre> and <code> block). Try to enter the attribute manually instead of copying from the documentation.
