So far, the update isn't going well...
I downloaded the updater, you actually need two files, a 44MB file, and a 10MB file, both of which need to be installed. Why would they do that? Second, if your device is connected while you are installing and running, you need to disconnect the device and reattach it. It will then act as if you’re installing the device for the first time and install USB drivers. Again, why is this part necessary? Lastly, the installer will stop if the battery is not fully charged. I’m at about 75% battery power, and it stopped and said please ensure you are fully charged, and then the only option is to exit.
I’ll report back in a few hours after the battery charges. Was this field tested before rollout?
