Personal docs, when sent to kindle, get stored in the cloud and can be re-sent from the Manage Your Content and Devices area. How what's the limit to how many things can be stored there?
I've read something about the Personal Docs being merged with the Cloud storage. When I go to
https://www.amazon.com/clouddrive/home it says that my trial has ended (never started one) and to start a plan in order to resume uploads. Indeed, my recent Send-to-Kindle items aren't there, but there are older ones. Still,
all docs can be re-accessed from the Manage Your Content area on Amazon anyway.
I've read that it's 5 GB for Amazon members free, and an additional 5 for Kindle users, but my cloud drive is at 10.1 MB used and as I said, it says I'm over the limit and isn't uploading any new Send-to-Kindle docs there.
So... what's the deal here?
