Howto sync trakt community ratings?

Hi all,
I already tried a lot options but it's still not possible for me to sync the trakt community ratings for
my tv series.
I already tried the new TVDB scrapper: sync doesn't work - always empty entries
Emby with trakt plugin: doesnt sync trakt, just tvdb ratings
Plex with trakt plugin: here the same, just syncs the tvdb ratings.

Does anybody know a possibiliy how to sync the trakt ratings? It's the biggest community with a lot of votes. Tvdb is very poor regarding ratings.

Thanks in advance,
