Not working with Kindle Fire HD

The [device] and [notdevice] shortcodes are being ignored on the Kindle Fire HD. Seems to be working OK on all other devices I’ve tried. Can you confirm that the Kindle Fire / Silk Browser user agent is included as a detectable device by this plugin? If not, can you add it?

Thanks!
