[2022] Xbox series X no coop possible after buying the game

Greetings Exile,

Thank you for reaching out to us. Can you share more details with us?

By any chance, the coop match host continued playing without the guest? We are currently investigating an issue when the host gets too far away from the guest, the guest might not be able to join the match anymore. Can you make sure both characters are close by and try again, please?

Please let us know if that assisted in your case.
