Hello community, I'm trying to get all of my library in one place. Right now, everything is saved in my Kindle Fire 10. I'm trying to get everything moved to the Amazon cloud so I can connect Calibre to it but if I use Amazon drive or ES Explorer, it doesn't pick up a lot of my books, mostly the ones I've purchased from Amazon. I can read them in the Kindle app but can't upload them. I've even gone to Amazon and had all of my purchased books delivered to my Kindle to see if that worked but they still don't show and I can't find where they're stored on my Kindle. All of my books from other sources I can see fine.

Also, when I try to connect Calibre to Amazon cloud, I get an error "unable to communicate with cloud provider". I've also tried to connect to "library on device", it allows me to choose paths to my books folder but when I get to the books folder, it does nothing. The only options I have are cancel or up\back.

I have a feeling it's user error and I'm just not doing this right. All I want is all of my books on a cloud so I can organize them and fix titles, authors etc and read them in any of my devices. Thanks in advance for any tips you can give me.
