For Sombra in the PVP beta for Overwatch 2, emptying the gun and then starting the animation, but interrupting it with a hack, sometimes causes the game to not let you reload for about a second or two after the hack (at least by pressing the shoot button). After that period of time, the gun reloads without the animation.
Also, the hacking POTG intro for her doesn’t work at all. It just causes a blank screen for several seconds until the actual gameplay starts.
