When playing Zelda: Breath of the Wilds on the Nintendo Switch, when I play with the Switch docked and the Joy-Cons physically disconnected, the left Joy-Con frequently "lags" or becomes disconnected from the Switch base unit altogether.
When the left Joy-Con lags, the Switch acts as though whatever input I had been using was still being held down. For example, Link will occasionally keep running briefly even after I release the analog joystick.
Only the left Joy-Con has this issue. The right Joy-Con always stays connected and has no lag issues.
The issue doesn't occur when the Joy-Cons are attached to the Nintendo Switch base unit itself.
The left Joy-Con does seem to work ok when it is within about 3 feet of the Nintendo Switch base unit, and there is no line-of-sight obstruction between the Joy-Con and the Switch
I have applied the "day one patch" to the Switch, with the Joy-Cons connected to the base Switch unit as the patch was applied.
There's also an article on the Nintendo Support site about general Joy-Con wireless connectivity problems. However, that article doesn't make any mention of the problem specific to the left Joy-Con.
My question: How can I resolve this intermittent wireless connectivity problem with the left Joy-Con?
