Hi all I hope someone can help 
Cross Platform Campaign Sync does not seem to work for me.
I understand mission checkpoints don’t save but I was under the impression that when I finished a Campaign Mission ( i’m playing Halo CE ) on the Xbox I could then continue on the PC ?
I’ve spent hours searching for a fix before finally coming here.
Do I simply have it wrong and this is not possible ?
I’ve read about resetting the Hosts file but mine was standard anyway. I’ve also tried turning my Firewall off but made no difference.
Both games are installed via Gamepass.
Thank !
