We recently made the update to 7.9.3 from version 7.5.2
From the list view in version 7.5, the preview is correctly observed.
When I click on the icon, the preview view shows all the fields that exist in the record view.
However, since we migrated to version 7.9.3, the preview view stopped working, because sometimes it shows only some fields that exists in the record view
and other times, when i click on the icon, it shows me an empty page
but the problem persists.
Thanks in advance
