I've defined actions associated with the Mode Shift Button (BTT Button 7) and the Gesture Button (BTT Button 6). For example, the Gesture Button Quick Click RELEASE triggers Cmd+Tab.
They work, but the problem is that they all stop functioning several times a day (perhaps, after computer sleep, but I'm not positive). The fix is to restart BTT, and they resume working.**
there have been lots of improvements in the recent alpha versions, maybe this is already resolved. New stable will follow in 1-2 days and be pushed to Setapp as well
Chiming in to say I experience the same issue multiple times most days. Seems mostly or entirely after wake from sleep. The Choose Connected Logitech Mouse dropdown in "Logitech Mouse Configuration" section loses the saved config, and I have to click Scan for Devices Again. Occasionally I also need to hard quit and restart BTT. FWIW, observe same behavior whether or not I toggle Restart BTT after wake from sleep in settings.
Additional context: BTT v6.521, MX Master 3 connected via Bluetooth, macOS 26.5, no Logitech software installed (or other non-OS mouse-control software), not new behavior (sorry I never reported earlier).
I just had this issue of BTT triggers stopping functioning, but this time it had nothing to do with a Logitech mouse. The trackpad gestures stopped. The BTT restart solved the issue.
