First, check your Roster Preferences settings on the Roster screen. It’s possible you accidentally flipped the switch for [b]Fireteam Privacy/invites[/b] to [i]Closed[/i] or changed [b]Invite Notifications[/b] to [i]Hide All[/i]. Second, check your Privacy settings on your given platform and in the D2 app to make sure they aren’t preventing you from receiving invites. (΄◉◞౪◟◉｀)
