Unable to connect to Online Adventure after latest updates, support have not helped

Looking for answers here at all, I cannot connect to an Online Adventure at all after the latest updates. Since launch I have had connection issues and support have only advised me to check their multiplayer guide, which I have and it hasn’t resolved my issue.

I’m on Xbox, my NAT is open and other games work absolutely fine.

Possibly the worst Forza game I’ve bought so far due to the unreliability of it.

Got same issue i can’t go on auction house
