I do not understand the attempt to justify. Regardless of whether IMDB always provides the name of the country using ISO 3166-1 alpha-2 (because the TMDB agent sends the full name except when no one has added the country of production), a Plex script must be able to convert those codes to the name of the country and offer a clean and consistent database. It is logical and reasonable.
When I say that the problem returned it is because a few days ago when adding a new library using the IMDB Plex Movies agent the country appeared with its name in all the movies but doing exactly the same a few days later they were added again with the code ISO 3166- 1 alpha-2. I do not know why.
Try yourself adding a new library using the Plex Movies agent and you will see that it happens. Regardless of whether TMDB or IMDB is selected inside the Plex Movies agent.
If you add a new library using the TMDB agent and secondly Plex Movies, the problem is solved. But I do not want to use the TMDB agent, I want to use the Plex Movie agent as the primary agent because if I use the TMDB agent as the primary agent it could not include Open Subtitiles or Cine Material.
Never in the many years that Plex has existed there was a problem like this. Always the country was deployed with the full name, how it should be, not ISO 3166- 1 alpha-2 code. It is a problem of the agent "Plex Movies" that the guys of Plex must solve. And it's incredible that they do not care.
