Me and my wife are both playing Grounded on each Xbox Series S. The issue is that a gray aim dot on my wife's screen is too tiny. And the size doesnt change for both first person and third person view. I can definitely see the difference, because we set up same 50in TV right next to each other. I couldnt find any option for adjusting the size of aim dot. Some ppl might think it is not a big deal, but it is barely visible especially during in-game daytime also giving a hard time to aim insects. Does anyone know how to increase the size of aim dot?
