I will ask Dune about the plan for future updates.
More than a week gone and still no response? Am I to assume that a device that was released just over a year ago will not be receiving the latest GUI and Alpha firmware whilst seven other devices are?
If so you might want to re-think the advertising you put on your Dune product pages!
