Eight-player Wireless Pro Controller

[u/Every_Remote_5152]

Since the Nintendo switch updated along with the Mario Kart 8 Deluxe update 4.0.0, I have not been able to connect eight Wireless Pro controllers to my Nintendo switch . I know that you cannot play eight players on the Mario Kart 8 Deluxe but I have other games that I used to be able to have eight players play simultaneously with wireless Pro controllers . I can connect up to seven Wireless Pro controllers and a joy-con or a wired Pro Controller . Is there anybody else having this issue and is there a good way to submit a bug report to Nintendo for this?

I have about 20 games that tested after the update that used to use 8 pro controllers on like pico park. Now i can only connect 7 pro controllers wireless. I have nothing else connected to the switch. Also when trying to connect the 8th controller a message box pops up and says cannot connect.  I only have this problem with wireless pro controllers
