If the Render dynamic data text on canvas feature is enabled, some widgets such as the Icon List will not perform the rendering process. But in widgets like heading, this feature works well.
I haven’t tested every single widget to see which ones have this problem. But it is definitely not limited to one or two widgets.
As you will see in the video below, I used heading and icon list widgets and used dynamic data {current_date} inside them. In the heading widget, the dynamic data is rendered well, but this does not happen in the icon list widget.
