The ArcGIS Instant Apps Attachment Viewer template does not display attachments in a map focused layout mode when there are several attachment enabled layers of which one is without features.

Solução Provisória

• Use an attachment focused layout.
• Remove empty attachment enabled layers from the underlying web map or add a feature to the empty layer (a placeholder does not have to be with the attachment).
• Use hosted feature layers.
