Impossible to say. The ePortal is still in development and lots of bugs to resolve. EMA of course is going through vast changes because of Brexit. EMA seem to have given up providing dates for the CTR into come into force. Some websites say that it might be end of 2020 but others do not commit to a date. When asked about the completion of the ePortal and hence the audit and then "go-Live" the reply was that this could not be foreseen at present.
