Are you even seeing it available in the app? When I navigate to Settings ➜ Device Info ➜ Firmware Version, the app is just showing me the ability to update from 4.51.1.8444 to 4.51.2.0379, as I mentioned in another topic, even though the announcement topic and the Release Notes & Firmware page indicate that 4.51.2.0578 should be available. I wonder if there was a problem posting the update, because I haven’t yet read any reports of anyone’s experience with this latest firmware.
