Now I finally have a second set so that I can send in my first ones for the connection issues

I've been having left joycon connection issues

I didn't have any connection issues

We also experienced some intermittent connection issues with the left joy con when seated farther from the console

I think the left joy-con don't have same connection issue that my launch joy-con has, but I haven't really investigated that in-depth.

Left Controller is experiencing the connection issue that is plaguing most Joy Con Controllers.

The joycon come with the Nintendo switch has connection issue

Good controllers but after a little under a year of use one controller is glitchy and has connection issues

It is a great controller if you understand it's limitations, it has connection issues frequently

The left, gray joycon suffers from pretty consistent connection issues
