Is that firmware version 4.51.2.0578? I understand that was paused for a while, but the Release Notes & Firmware page shows that it should be available again. The app (both v3.0 and v2.5x) is still showing me only an update path from v4.51.1.8444 to v4.51.2.0379, so I don’t know if there’s still an issue with the roll-out or if it requires a stepwise update.
I’ll plan to ask about that in the announcement topic if I don’t see it within another day or so.
