Not the OG campaign. Not Operation Spearbreaker. Just ATN. You fixed it last time, plz do it again.
I have the same issue but worse because all my progress from all three campaigns are gone not just AtN. Not only that but any new saves I make just vanish the moment I turn of the console. An update from between Oct. 31st & Nov. 2nd was supposed to fix that but it didn’t. Another user said he called Xbox Support and they told him to both check his internet connection & change his DNS. He says it’s worked so far and recommends you check to make sure that the IP address is static (whatever that means). I hope that helps.
