It is still not possible to import data from repeater or cloneable fields or relationship fields with WP ALL Import Pro?
Sorry, but this should be a matter of course.
I've had a license from you for a year now, but I've never used your plugin because you don't offer a professional way to import data.
That's why I use ACF Pro. For this plugin there is a very good add-on for WP All Import and WP All Export.
