Hello,
I am unable to chat in game. I can chat in parties and any other multiplayer game but not dayz.
It is not related to push to talk or voice activated settings.
So far I have tried the following:
Uninstall and reinstall
Clear the save game info on the xbox
Static ip for the xbox
It seems like it has happened to a few people based on searches online.
My username is the same as my site username.
