Amazon disappointing

I changed "Death in Durrington" to OpenDyslexic Font. All went well until I tried to preview it on Amazon and found they had changed it back to a conventional font.

The response from Amazon was disappointing

Hello,

I understand your concerns about using Open Dyslexic font and the conversion result.

Please note, some dyslexic readers may prefer the Open Dyslexic font. This font is available globally and works for reflowable book formats only.

This font is available for readers to select on IOs and eInk devices, but it is not currently available on Fire tablets or other devices and I'm sorry at this time we've no workaround for this issue.

Although at this time there is no option for this, we'll be sure to consider your feedback as we plan for further improvements. Please be sure to check our forums periodically for updates:
