Discontinuation of Plugins, Watch Later, Recommended, and Cloud Sync:
Q: Will scanners and agents be affected?
A: While support for browsable plugins is being discontinued, nothing is happening to scanners and metadata agents with this announcement.
Т.е., насколько я понимаю, текущие проблемы с агентом Кинопоиск не связаны политикой Plex отказа от плагинов.
Хотя, конечно, это свинство с их стороны.
С другой стороны:
Q:When will these features get discontinued?
A: The Plugin Directory will be removed from Plex Web App in an upcoming update on Oct 9, 2018. You will still be able to manually install plugins on the server itself, even after the Plugin Directory is removed. Watch Later, Recommended, and Cloud Sync will also be removed starting in early October, and will vary between each player app.
