garmin.openstreetmap.nl (again)

I read your PDF.
But Maps.me 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.
https://organicmaps.app/

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
http://osm.dl1thm.de/openfietsmap/benelux/full (or light
or hike or germany) but the NLUUG server is not synchronised.
