I'm trying to report iOS Kindle App to Amazon but seems an impossible task to report bugs to them.

php?p=4131186& postcount= 8Īnd here is the entire thread: https:/ /showthread. This is the post in Mobilieread cited above that clarifies the issue: https:/ /showpost. I've created a rule in Look & Feel -> Transform Styles that replaces a value >= 20% by 10em in 'margin-top' and then the conversion seems done right but still starting of each chapter is shown very strange. I can add that with a value of 20% in that property still happens, and the workaround I've found reduce the issue but not eliminate it. So one possible fix to to use that instead of calibre for this conversion.' I converted the EPUB to MOBI using Amazon's Kindle Previewer and in the MOBI file that it creates it leaves the value at 33% and this works OK when loaded into Kindle for iOS. The MOBI renderer obviously should not be doing that, but it is somewhat of a garbage-in garbage-out situation. This in turn appears to trigger a bug in the MOBI renderer under iOS, causing the paragraph to start on the next page with some of the initial text missing. In the MOBI file produced by calibre that 33% is changed to instead be 150em, which is an unreasonably huge value! That looks to me like a calibre bug. Percentage for a margin is based on the width of the container so for a typical portrait page orientation that should make the paragraph start about a quarter of the way down the page. 'The EPUB file has a class named saltoinicio which sets margin-top:33% for the first paragraph of a chapter. I'm pasting here the explanation given by 'jhowell' user in Mobileread as it describes the exact problem in great detail: Happens in Calibre 5.21.0 under macOS Big Sur 11.4 and as far as I remember since a lot of previous versions because this issue made me stop using Kindle apps for reading non Amazon purchased books. This seems to be a combination of a bug in iOS Kindle App and another in Calibre mobi converter.
