Just for more clarity on my side, please provide a short answer to the follwing questions:

Does the ratings update with "Episode" mode of Supernatural finish or not? - No
Does the ratings update with "Season" mode of Supernatural finish or not? -  Yes
In general, how long does it take an update of a single TV show (through context menu)? 12 seconds on an average 6 part series.
Is there any difference between "Episode" and "Season" modes in terms of elapsed time (for a single TV show)? - Epsiodes mode does not function, only Seasons. This I believe was addressed by @Karellen in a previous post.
Independently from whatever TV shows do you have in the library, the ratings udate of the entire library stucks always at 6-7%? - Yes
It happens for both "Episode" and "Season" modes? - It used to happen in Episode mode until that stopped working, but only happens now in Season mode.

Hope this helps.

Hi @shedrock, thanks a lot for answering.

It is quite strange that the Episode mode does not work even for the single Supernatural TV show; indeed if in your DB you don't have the IMDb IDs for the episodes, the add-on search for them on TMDB (i.e. it retrieves the IMDb IDs for each episode and then update the ratings accordingly). I have just checked on TMDB site and the IMDb IDs for Supernatural episodes are actually available...This means that the ratings update using Episode mode should work properly. So, when you say that it doesn't finish, what it exaclty means?

What @Karellen wrote is correct. Anyway the point is that if IMDb IDs are missing, people should make the effort to add them on TMDB site helping at the same time the entire community. Under this assumption, the Episode mode is going to provide the best result with respect to Season mode (even if slower).

The fact that the ratings update always stuck at 6-7% independently from your library content (i.e. number of TV shows) is really somethig strange that I can not explain (and the logs don't show as well). The only thing I can try to do is to perform an update on my machine if you send me your Kodi video database located in the userdata folder.

Have a great afternoon (at least here is afternoon!).
