So I’ve played a couple of Warzone Firefight just a little while ago. And when I tried to use reqs. It would just kick me out of the req menu and back into the game. I tried multiple times and I could not use any. And yes I has to required req level and match points to use said reqs. I could not even chose different weapons such as the Assault rifle or Battle rifle. I don’t know if its just me or other players have this problem but I have seen other players have use reqs such as vehicles.
Sorry for the late reply OP, you can try doing a hard reset of your console and see if that helps (unplug the power for about a minute and switch back on)
I was able to figure it out after awhile. Hard Resets didn’t do anything. I had to Re-download the full game but it works now. My main point when I asked about this was to see if anyone else had this problem. But thank you for your advice.
