Just got the keyboard. Love it. This below un-documented function took me a hour:
To switch left Ctrl and left Win, hold Fn + left Alt for 3 seconds until backlight flashes 3 times.
zhigangYou've saved me! Somehow I must have triggered this undocumented key combo and was driving myself crazy trying to hunt down a fix. I love this keyboard so much and I was very worried. Massive thanks for figuring this out and taking the initiative to post your finding!
zhigangThis is absolute gold. it was literally driving me crazy and there's little to no documentation on how to fix that or just go to factory default settings.
