Multiplayer on Switch isn't the best, and it isn't really CA's fault.
It's plainly the Switch's processing power, it runs fine singleplayer but multiplayer can be buggy at times, the only way that CA could maybe help with fixing this would be to make low performance mode.
If you can mod your Switch then I recommend it, it can truly open up the capabilities of the Switch processing power!
