It really does have middle click - but yes, not on the wheel. See this image: https://www.gottabemobile.com/wp-content/uploads/2017/06/logitech-options-software-button-configuration.jpg https://www.gottabemobile.com/wp-content/uploads/2017/06/log... On the left image, the lower, centered circle above the green light highlights the middle click. I'm using one right now, and I can click it to open links in a new tab (by default with no changes in software.) Works in Firefox under Linux Mint and Windows 10.
