App – image_default_link_type for Lightbox

Problem: creating a post from iOS/Android WordPress App with images, does not use, as default link-settings, “media”. That cause a problem with lightbox plugins, to view the images in a lightbox.

Is there a solution to automatically set “link-settings” to “media” for posts made with mobile app inside the app or wordpress backend.

Set “image_default_link_type” to file works for posts made on web but not for mobile iOS/Android App
