Does it work yet? How to make models appear in iModelHub?

 I've managed add required roles for users to deal with iModelHub. I've connected PW repository to the Cloud Project. I've created Base iModel (an empty placeholder) in iModelHub. I've mapped one, then more, then even more DGN and I.DGN files to that Base iModel. I've made lot of changes in various mapped DGN files, incl. version changes. But....... nothing appears in this Base iModel - no Changes, no Views, no User activities are captured. It just stays empty. How?
