Timetable for buses in Haute Nendaz (Switzerland)

I'm planning a trip to Haute Nendaz next winter and looking at some accommodation options, some of which is bus ride away from the ski lift. As part of this I was hoping to find a timetable but have been unable to - the routes are described at: https://www.nendaz.ch/en/free-shuttle-buses-fp44533.html for the winter season but clicking the times link takes you to a page for the summer season. The buses don't appear on Google maps and the page is not indexed in the wayback machine.

Is there any other source of the bus times? I accept the exact times for the next winter season may not be known yet, but even a timetable from previous winter seasons would be a huge help - my experience from previous trips as that from one winter season to the next most changes are very minor and except the risk. But that changes between the summer and winter season can be very significant.
