I can write with the same keyboard between two devices.

to switch between devices, I press Function + the number pf the device

For instance, this laptop is currently set to no1

iPhone is no2

it seems to bee working alright at the moment...

Let's try and time the amount of time it take to switch...

kk

Although the keys' backlight goes off, the keyboard switch is functionn


I now believe the change happens very quickly @ around 2 seconds
