Was waiting patiently for it, but turns out it's onl for the DN360 & DN372 according to https://support.youview.com/youview-box/software-updates/talktalk-software-update-60-43-106-72-43-106
They state "... DN370T device will receive this update at a later date". So end of the queue for all of us stuck with this box.
Anyone any idea when this will be?
