I just purchased an eARC copy of an forthcoming book in order to help spot typos. I managed to get it to register on all my Kindle devices (a Paperwhite, and an iPad and iPhone kindle app) and highlighted/bookmarked the typos. But now I find that my Amazon online account does not show me this document. Is that always the case with downloaded docs other than Amazon purchases then? Or is there a way for me to see these bookmarks online?
