I have sent the log file.
The thing is, that I was able to do the same thing a few weeks before replacing the Argon gateway network with the xenons with a new Boron based one. And a few weeks before that when setting up the new HW for the first time with the Argon as gateway.
As I recall, a firmware update where only requested when I originally set up the Argon based network for the first time early January, and not when I last changed to a Boron gateway [2] weeks later.
So apart from a new App version, I guess the firmware upgraded from is different.
