Subject: Bug Report: Swipe Gesture Not Working for Custom Setting on MX Master 3S (macOS 26 Tahoe)

Hi Logitech Support Team,

I am writing to report a bug with the Logi Options+ software on macOS 26 Tahoe, affecting my MX Master 3S mouse.

When I set the mouse’s thumb navigation to “Custom,” I am unable to use swipe gestures (left and right) as expected. The gestures work correctly under “Gestures App Navigation” (except for Launchpad, which is now missing as an option in macOS 26 Tahoe, and App Exposé, which I don’t need). Since Launchpad isn’t available, I wanted to switch to custom gestures to configure navigation more flexibly. However, when custom gestures are set up, the thumb swipe doesn’t function the same way as in the default app navigation mode.

This is a key feature for my workflow, so I’d appreciate your urgent assistance and a fix for this issue.

Thank you!

Best regards,
