Thanks for posting. You may have confirmed a question I had for our devs. They just mentioned that invoices in the CMC aren't viewable today, and I wasn't sure if that applied to all customers, but looks like that may be the case. I would think this is temporary while they are working on some CMC updates. I don't have any ETA yet on the updates.
