Anywhere from a week or until never...KALY is proof of this which ran big after they got the CE, though they rushed to put an atty letter to remedy this which OTCM couldn't care less about right now.
At least DNAD waited until a month to pass which is a smart move and have seen many get reinstated if they wait that long so if everything is Kosher, the CE should be removed in a week or two at the latest, imo.
