Seems like they are not actualy giving us updates.
Firmware that you get when you buy it, is the one you end up with.
I have a few 1TB Ultra 3Ds, not a single update came in last two years.
They even have a diffrent firmware versions.
I didn’t even get the update for the drives with older version, to reach the newer one that I have.
Seems like a bad support on their side
