Yeah, I noticed the issue with the left Joycon as well in my half hour trying the grip. I found it was my left index finger on the trigger blocking the signal. That Joycon was completely unresponsive when I held my finger a certain way. I had to kind of hold my finger away in a ready position if I felt like I needed to hit the trigger soon. I wasn't able to replicate it with the right side.

I've mainly been using the Pro Controller, though, so it hasn't affect me much. Definitely disappointing, though.
