I just started playing the Switch again. When I initially bought my Pro Controller there was something wrong with it, sends my characters in wrong directions, input lag, and disconnects. Sending it to Nintendo is a PITA. I wanted a second Pro Controller for my girl so we can play MK8 (she hates the regular switch controller) so I bought a second Pro Controller, kept it and swapped my broken pro controller into it's box and exchanged it for a new one, and voila 2 brand new working pro controllers. Now I think I am going to have to send in my Joycons because they are doing the same thing, input lag, disconnecting, blah blah.
