Middle Mouse Button (M1 Mac + Razer Deathadder V2)

I am unable to get the middle mouse button to work on my M1 Mac. I have done quite a bit of research and it seems like there just isn’t an option. Has anyone had success or is it time to ugprade to the Corsair Scimitar MMO mouse? If I upgrade what will I need to get that mouse working correctly?

I am having a similar problem. My left and middle mouse clicks suddenly stop working. I’ve reset the UI, disabled addons, etc. Everything works for about 15 minutes. Even with USB Overdrive. I even bought a new mouse. Now using a Venus MMO mouse and still having the same problems. Everything works fine for about 15 minutes, then I lose the click. I can use the camera view fine however, so something’s fishy!. Only started with the latest patch.
