I saw in a closed topic on this from others.
I have same issue now. I’m new to Razer - Basilisk v3. Synapese 3.8 has cloud sync with profiles.
When I switch - with USB switch, between 2 computers, I also experience - sometimes, approx. 50% of the time: my profiles get duplicated - like My Profile (1), My Profile (2), etc. The duplicate Profiles are usually empty - a reset profile. But this is unacceptable. Basically, using the mouse on 2 computer is now not possible - withour 50% time needing to manually fixing the profiles.
