      cards:
        - type: custom:upcoming-media-card
          entity: sensor.asd_plex_recently_added
          title: Recently added. . .

          date: ddmm
          max: 5
          image_style: fanart
          hide_flagged: false
          hide_unflagged: false
          flag: false
          text_shadows: true
          box_shadows: false
          enable_transparency: true
          disable_hyperlinks: true

Troubleshooting Guide:

I found a small workaround stacking it inside of button card as custom_field, that way it displays but if you using fanart as I do, the text is misaligned (to the right)

Sorry I have no idea. I've never used swipe card before nor CSS swipe card.
