This is a new post created with WordPress 5.1 “Betty” and the DICOM Support plugin 0.7.2 (sorry I missed WordPress 5.0 “Bebo”).
For now, you cannot add dicom views with the new ‘image’ or ‘gallery’ blocks, you need to use a ‘classic’ block and then choose the ‘add media’ button.
Stay tuned for an update on the new WP5 api integration…
