Hi,
we can display the first attachment on page load.
Unfortunately, this only works if the attachment is not displayed as a popup.
Even if the documentation is updated to mention this different behavior. I find it counter intuitive that this should be a different
Instead of changing the current way, I would prefer a form rule which can be used to display an attachment in the preview. This way we wouldn't be limited to the first attachment but could get the attachment to display with a business rule or similar.
Best regards,
