thanks, got your config and macro.
and we import them into our cross hair.
but find no error or conflict between them in fortnite.
mouse is G502 too.
here are some things you may also try:
1. restore your cross hair to factory default,
by following instructions in our manual "CrossHair-UserManual-V5.1.pdf", page 37-38.
2. add only one config(fortnite) in ps4.
do not change it, do not add macro in it.
then save.
3. do not connect keyboard to cross hair , just connect your mouse to it.
then try the left button on mouse.
4. use another mouse, a simple one, make sure its buttons are not programmable.
try its left button on mouse again.
