Anyone experienced with ebooks and publishing on IngramSpark?
I’ve finished exporting an ebook but when I upload to IngramSpark the system gives me this error. I assumed that there was a problem with the date I entered in the metadata in InDesign prior to exporting, but I removed the date entirely and it still gives the same error.
Perhaps the date needs to be formatted a specific way? Or maybe I’m completely wrong and the error is something else?
