With the new mods presenting rotten tomatoes, metacritic etc, i've noticed once you scan the library, the rating wont update/change in the future
I can only update/change imdb rating via "rating update addon"

Is there a workaround for the rest?

Because I don't live alone? That's why the profile feature was built into kodi. My library/trakt.tv account is different from my wife's.

You missed my question. Anyway, i just ran a quick test, setted up 2 profiles and worked without defaulting. Maybe you need to save and correctly restart on profile 1 and then create profile 2 save and repeat.
Furthermore, you have to configure profile 2 the way you want it, or it will default every single time. My advice is to export skin settings and import when on profile 2.

Exporting settings for each profile stopped it from defaulting when switching. Thanks for that. It's not obvious to me why one would need to do that to get the settings for each profile to stick, but whatever works.

Now I can't seem to get poster and fan art to show up when switching views. Poster art (but not fan art) shows up when using the default "Right List" view.

Are you using local files on artwork downloader?
