With mine it went from 10% of the time to 95% of the time. I still get the occasional double click not working if I try to do lots together.
i.e. create 20 MIDI tracks and then double click in each one to create a MIDI part one after the other with no rest in between occasionally one part won’t create. If I leave it for a split second between creating parts it always works.
Make sure your batteries in your mouse are healthy and then try adjusting the double click speed in System Preferences > Accessibility > Mouse - mine is set to around 80%
