Does not sync with all devices

I use the Kindle reading app on my iPhone and my iPad seamlessly. My pages are always synced up (sometimes maybe one or two off, but cloes enough that it doesn’t bother me at all). With the desktop app though, it does not sync pages, and my collections are missing. I had hoped to use the desktop app to “clean up” my collections for my devices, but since they don’t sync, what’s the point? The Kindle app is great to read on, and I would still recommend it to people, but this needs to be fixed.
