Hello friends I have suffered in silence for 30+ hour of not earning exp, req and competitive rank… annoying. But I have fixed it.
What I did was unplugged my portable hard drive “in theory unistalling the game” then proceeded to delete my accounts, disconnect the internet then hard reset the console by pulling the power.
After turning my console back on proceeded to plug a wired connection in to my xbox then recover my account, then plug my hard drive back in then loaded up and played a game of swat and everything seemed to be all good.
hope it helps.
