Hi all! Playing MCC on Xbox Series X. I did the first two missions of Halo 3 LASO with friends a few weeks back and never finished. Just finished ODST LASO yesterday solo so figured I’d continue H3 LASO from where we left off. Only issue is I cannot resume the playlist. Every time I try I get the dreaded “your connection to the session has been interrupted” even though I’m the host. Is there any fix for this, or do I need to restart the playlist?
