I never get any notifications when I receive an invite from a fireteam or a friend request. The only way I know if I had an invite is if I go to the roster tab and manually check it. How do I fix this? Also on a side note Bungie, your friend list sorting is god awful. Should be able to sort by recents, current class, or by mission/ strike, etc. Right now I have to click each person's name to see if they are doing something I want to join/ if they have room available. I have to inspect them to see what class they are on at that point too.
