I remain surprised that, if you download the sample of an Amazon eBook to the Kindle app on iOS, read it and make some highlights in it, then proceed to purchase the entire book, the Kindle app loses your progress and highlights.

This is a “success” path for the Kindle business, isn’t it? Seems like they’d want it to not leave a sour taste every time. Does it (still) do this on actual Kindle devices?

In any case, it seems like a good way to make me more likely to pay a higher price for the (nearly always nicer looking) Apple Books version of an eBook (when available).
