I mentioned yesterday that I was having major problems trying to reupload Hidden Boundaries after changing the cover. Okay, more than mentioned; I whined. Anyway, I let the customer rep know that I’d solved the problem by changing from .doc to .epub. And I thought that was the end of it. Today I get another email, letting me know that the problem was with the version of Word that I’d used. KDP no longer supports anything earlier than Word 97. Apparently that changed since my original upload in February. So if you’re using Word, make sure you don’t use older versions.
How often does a big company follow through that way? Awesome.
