And all it took was an email to the support team. If you know me personally, you may appreciate the irony.
The problem I was having was that the Kissing The Scorpion book description on the UK app store was displaying as an ugly paragraph full of visible HTML tags. On Amazon.com (US) it was displaying properly.
It didn’t matter what I did, I couldn’t fix it.
Eventually, after getting some advice on the kboards forums, I tried using the support contact form within KDP (Amazon Kindle Direct Publishing) and it was sorted out within an hour.
Thanks to whoever sorted it out – it is much appreciated!
