Logitech! What is your **** problem!?
The MX Master 3S is one of your most famous and expensive mice!
WHY ON FREAKING EARTH HEAVEN AND **** is it not supported in the firmware update tool!!!???
People are stuck with super old versions of the firmware while new batches come with the newest firmware.
Everybody knows. Internet is FULL of such complaints.
You are by far THE one single Company that gives the less **** about customers!
In the EU such a policy is even illegal. You can't release new batches with new firmware and let the others with a faulty product!
Change this RIGHT NOW!!!
