Hello. So on my solar warlock, when I hold LB (xbox) to charge and consume my solar grenade, it works sometimes and other times it acts as if I tapped LB (to throw the grenade). I thought that maybe there might be something wrong with my controller so I went to the Xbox accessories in settings. I then went to testing. It shows that my controller is okay and when I hold LB, it shows that I, indeed, am holding LB. What can I do to get this to work?
