Hi again,
seems I got it working meanwhile.
What I did: I was sending all the books to my new reader. After that updated the Metadata on the reader and disconnected the device.
Nothing synchroniced till there.
So I just connected the reader again, only updated the readers metadata once again and unplugged the reader.
Now my read book are marked as such on the reader
Strange, but it seems I must do that twice.
However, is there a chance to do this with my wives reader to? Of course she has read different book than I have, so she does not want my reading status on her reader.
What happens if I make to collumns in calibre, one for me and one for my wife, and always deaktivate the column which does not belong to the connected reader? Is the column still working when it is not activated / visible?
Stefan
