Logitech MX vertical on Mac not recognising unifying receiver (easy switch position 1). How to fix

In case your mouse stops connecting the the USB receiver (that works way better than bluetooth, at least on my M1 Mac), here is how I fixed it:

• download Unifying software from this link. Note: it’s not LogiOptions+, that app is not enough
• Install `Unifying Installer.app` and alos allow input monitoring permission. then click quick and reopen

• launch Logitech unifying software using spotlight

• Switch off the mouse, switch easy switch to 1 and turn it on;
• The app told me to pair, but I didn’t need to do that, maybe because it was alredy paired in the past but it misteriously stopped working;
• It shoud now work. Delete the bluetooth setup in case you don’t use it to make sure you use it with the receiver
