Can't upload the result files to Kindle or Google Play Books

[bbeam23]

I got the EPUB file but it can't be uploaded to the apps. It just says error. Does this still work?

sorry, I don't have kindle or android devices, so i can't investigate this issue.
But I guess this may be related to HTML tags. the EPUB use SVG tags to display images.

I add a new option in the page setting dialog, hope it can resolve your problem.

Thank you for trying to fix the issue. But it still failed, unfortunately.

I'm testing the file with an app called Kindle Previewer and this is the error message:

Hope that helps! You can also try the Kindle Previewer app yourself to see if the result file from your app can be conversed and opened in their app. If it can go through the conversion then there shouldn't be a problem uploading to Kindle.
