So I just went to update the firmware on my 2017 Zero DS, and the app says I have to take it to a dealer for the update. I just read that another owner had exactly the same problem at the end of 2017:

Currently I have firmware version 12 and I was wondering if anyone has managed to update it themselves. I have both android and iphone to test.
