I read your PDF.
But is like dead. A good replacement is Organic Maps. It even allows you to do simple edits in OSM; I have used it a couple of times that way.

May be change your pdf again ?? :wink:

Is this issue already sorted ? (When we can download OFM updates again? )

No unfortunately not yet.
Updates can be temporarily downloaded from (or light
or hike or germany) but the NLUUG server is not synchronised.
