Hi
Apologies for digging this one up. I was having the same issue with 3 finger tap to Middle Mouse Click. I have found a solution than can be used when Tap to Click and 3 Finger Drag is enabled in MacOS. In BTT do the following:
- Add 3 Finger Tap and assign Middle Mouse Click action to it.
- Add 3 Finger Click and assign Middle Mouse Click action to it.
Yes, it's a duplication but seems to help with the issue, at least for me. Now 3 Finger Tap acts as Middle Mouse Click without issues. Otherwise with just the 1st one 3 Finger Tap was working intermittently.
