Is anyone else having troubles updating Tacx Neo Smart Bike firmware from 0.40 to 0.41?

I've gotten repeated failures updating Tacx Neo Smart Bike firmware from 0.40 to 0.41. Previously with the Utility App, now with the Training App. It progresses about 15% or so, then it says it's rebooting and progresses no further. Tacx support keeps telling me to disconnect, unplug for an hour or more, and try again. But I've done this a dozen times already, and the update still fails. Could it be the bike? Should I ask for a warranty return or replacement?
