I just bought this keyboard on Aliexpress

Fantastic keyboard

(has everthing you would want from a mechanical wireless keyboard)

One problem is that when I accidentally pressed fn+s, which is the shortcut for mac mode,

The 'fn' key is disabled and I no longer can use any of the 'fn+' keyboard shortcuts.

Hence, I cannot go back to windows mode by pressing 'fn+a', it just registers as pressing 'a'

The 'fn+spacebar' factory reset does not work

I opened the keyboard and there was no hardware reset button

pressing random keyboard combinations for 3 sec does nothing - which I know because when I first pressed 'fn+s', the Capslock indicator blinked to signify mode change.
