I'm using Amazon Photos for cloud storage of a bunch of Live Photos I take with my iPhone. I can view them as Live Photos (and play the video) when viewing them on photos.amazon.com, and I can also view them this way when I import them directly into the Mac OS Photos app. Here's an example photo on Amazon. However, when I download it (using the download button on Amazon Photos) and import it into Mac OS Photos, all I get is a still image. How can I get the Live Photo or even separate video and photo files (which is what I get when I export from Google Photos)?
