Whenever I want to use one of my PLD cool-downs, it seems like the only way I can trigger them is if I tap the hotkey multiple times. Nothing will happen if I tap just once.

I know they're off the the GCD because I've seen them trigger in-between GCD combo attacks -- but I'm wondering if anyone else has had similar issues. This only becomes annoying during intense encounters where I use them, only to realize 15 seconds later that they never triggered even though I know I pressed the right key.

I'm playing on a PS4 with a DS4.
