I'm taking up the task of publishing some content to Kindle. I've been reading up on their documentation and been trying to get something to show up in the Kindle Previewer App, using a combination of Microsoft Word for Mac, Pages, and KindleGen, but without any luck so far.
Even when using Pages to export simple text (Body format, Times New Roman, 12 point size) to ePub, then using KindleGen to export ePub to .mobi, Kindle Previewer says "An unknown error occurred." I've also tried having Kindle Previewer open the ePub, but I get the same error.
I'm trying to find some good resources for publishing to KDP and thought that this community would have some experienced people.
