Can someone speak to this?

I'm asking because I have a Nintendo Switch and I play games with split Joy Cons in docked mode, my right cons have been absurdly unreliable and I'm trying to understand the reason. I've had 4 pairs but they all suffer and the left never does. The console is to my left and my laptop with the Logitech dongle is to my right so I wonder if that has something to do with it. Turning off my mouse seems to help but maybe I should be removing the dongle too...
