New Kindle Fire owner here. Was running on 6.1.something, and all seemed well. Pressed "Sync", which apparently upgraded me to 6.3.whatever. That was great, as the parental controls are just what I was looking for.
HOWEVER, the App Store is now completely, totally unusable. I go to the store, and it's like my Fire's CPU clock was dialed down by a factor 1000. I cannot scroll apps, or catogories. I can't select an app to view. Completely unusable.
I can't say for sure that it's related to the SW update, but that seems to be the case.
