I've been trying to figure out all day why when I start the beta why it keeps telling me that i've been disconnected from the server. This message displays right after the intro title and only allows me to quick to desktop.
I've noticed some other ppl having the same issue and I think I found a solution (At least it worked for me).
1. Go to activision and login to your account and unlink battlenet
2. Close battlenet and restart it
3. Open COD MW and follow the prompts
It doesnt even let me unlink my battle.net
Biggest waste of money
I have the same issue. This workaround worked for the beta but rn on activision/callofduty.com, unlinking bnet ist not possible (error message).
