They mean it for the players who haven’t merged. In the in-game main menu under account merge it shows your queue in the merging process. Other than that we the individuals who did this in OW1 are screwed until further notice XD
You can un-merge on your BattleNet (don’t worry about the massage that you can’t merge for 365 days - this only happens if you make another account. Using the same one is safe) - and then load the game on your console. When the queue hits 0, it asks you to scan a QR-Code - I did this multiple times but still can’t play
