update 11/5/2019 9:33pm eastern 3 separate support sessions, the most recent decided I needed an RMA. it arrived today and I decided to give it a shot, to continue with the support process. loaded everything up, set it to charge and headed out for a little while. upon my return, everything was wiped as before. not surprised, something's up with the software on these things. i did try the delete app cache/etc for kindle app itself on the fire, but that did not work either. i havent heard back from the escalated person I was working with in a few days, but they definitely have some reading material from me when they are able to get to it. stay tuned!
original review text: after multiple support requests, amazon wants to "replace under warranty." there's nothing physically wrong with this device, it will just delete all of your downloaded content while charging. its pretty much garbage software, the hardware is great though. really frustrating.
