You can save your user settings as a profile (or multiple profiles). You can save these profiles to your card prior to a firmware update and reload them once the firmware update is complete to reestablish your settings.
Would it be nice if they asked if you wanted your current settings to be saved to the SD card (or your device if you are updating over the FOTOS app) as a temporary profile? Sure. But they don't. Now you know to do it yourself!

The idea that I would have to somehow be active in securing my settings, whether encouraged or not, is downright absurd. I haven't had to do any of that with Canon, Sony or Fuji.
It's just a firmware update. Factory reset should be no one's default assumption.
Yet here I am, with a more expensive camera than any other camera I've ever owned, and this is somehow normal?
I love Leica for what they're good at (good core technology and design). But bad SW execution is not acceptable in my books when you're selling luxury gear.
