I have a layout with a number of elements.
Several of the elements will not export to a PDF even though they are visible in the layout
Below is how it looks in Pro
This is how it exports. The disclaimer is missing. There is also an element above the scale bar that I turned off for the example because it contains email addresses
The missing elements are sized to the same size as the element containing the Ticket number. They are just text boxes and not dynamic
That's frustrating and odd. What version of Pro are you using? And are the missing elements on the page? Pro will allow you to draw elements off the page on a layout, but only the elements on the page itself will be shown in an export.
