Logi K860 wireless keyboard Opt/Cmd keys swapped

When using a Logi K860 Ergo wireless keyboard, Cmd and Opt keys are swapped.

This happens from time to time and also on Windows.

I am posting this question to also provide the solution which I have found after a lot of research, hopefully it will be useful to other users:

• Pressing and holding on K860 keyboard, for at least 5s, the combo fn+O resets the keyboard layout to the MacOs layout (Cmd is Cmd, Opt is Opt)
• Pressing and holding on K860 keyboard, for at least 5s, the combo fn+P resets the keyboard layout to the Windows layout (Cmd is Alt, Opt is Start)

Please note the fn key is the one between Cmd and Opt on the right side of the keyboard.

Hope it helps!
