Super Series ... but where are the result of 3 and 4?

The series is really well done. As one would expect from just the BBC. I knew a part of the series already from the UK and I am glad that Amazon offers this. But what I absolutely can not understand is not provided by the Amazon episode 3 and 4. On demand at Amazon it said that it was not possible to tell from lizensrechtlichen to when these episodes can be provided. ???
In other words, you no longer get well. Very annoying and incomprehensible. At least not for me. I sincerely hope that Amazon will subsequently supply the consequences yet.

Update:
Many, many thanks to Amazon. They actually submitted the consequences 3 and 4. Very commendable.
