@SRSly Most likely there just aren't enough player base for now. I'm seeing the same reports for Destiny 2 PvP matchmaking and GRID's 40 player endurance test.
I was actually hoping GRID would be one of December's game for Pro subscription. Really want to check out the 40 players endurance mode that's only available on Stadia.
@Ivan I figured. Just wasn't sure if I missed something. I'm with you on hoping for Grid as a Pro game. It has me intrigued, but I'm not enough of a racing game fan to pay full price for it.
