I am using cross-save between xbox and steam, I play on steam with characters originating from xbox. Any fireteam invites I receive go directly to my xbox when playing on either pc or xbox. It is incredibly frustrating having to "get a ride" from a friend into a raid or LFG team because I cannot receive invites on my main platform. I either need help from a saint or @bungie NEEDS to fix this neglected cross-save issue.
