Looks like I’ve made a schoolboy error and uploaded the unproofed kindle file rather than the proofed version. It is now live on Amazon with the stupid mistakes I’d made now corrected.
If you bought it over the last few days, hopefully you will automatically get an updated file, but if now then please follow amazon’s advice –
Amazon UK –
Amazon US –

If you’ve already purchased your book and subsequently revise the content and re-publish the updated version, you don’t need to re-purchase the book to get a copy. At this time, it’s not possible for publishers to receive the updated file without contacting KDP Support for help. We’re working to automate this feature and appreciate your understanding with our existing solution to manually send the updated content to your device.
We request your explicit permission, and will do the same for any customers who contact us to receive the updated content, prior to sending the revised file because the new version will not have previously saved Highlights, Last Page Read, Bookmarks, and the location of notes may not match. If this is acceptable, please email confirming your permission and which title/s you’d like to have re-sent. Thank you.
Note: Customers who purchased the old content can also contact our Customer Service department to have the new file delivered.

Thanks to everyone who’s notified me – I’d been offline for a few days so wasn’t aware till I saw a 2* review on… 🙁
