Fortnite suddenly no aim?

I started fortnite again 4 days ago with a 6.50 sensibility.

I was able to play very well with them for 3 days and not since yesterday at all. Why is that? Should I just keep playing with the sensibility?

PS: Adjusting another sensitivity brings nothing there's the problem again after a few days because that's been going on for 6 months

Maybe someone knows what?

You also should not always change, commit yourself to a middle and hold that too, if you always change you do not improve yourself at all
