Incompatible Realms after update

Hey Folks, Sorry for the troubles you experienced earlier. This should be working again. If you are still seeing these issues, please exit the Battle.net application and restart it. Once restarted, please navigate to your World of Warcraft tab, then click on the cog icon and click check for updates. This should allow you to revert the client to 10.0.7.48865 and play once more.
