Since the pre-patch for Fractured in Alterac, most of the times I want to play Battlegrounds, the game freezes just before the hero selection, with the screen shaded, just like in this screenshot imgur(dot)com/a/CC3UeXb
The damage protection animation still plays though, the game is not completely frozen. I have to force shut down the app and relaunch it, with luck I arrive for the second turn, or even the third, ruining the match. This doesn’t happen on PC.
