I noticed lately that on the Plex home screen there is seasonal genre line of videos. Around Christmas there was a line that was a grouping of Christmas movies. Now I’m seeing a line that is called “love is in the air”. It appears on all my devices including Plex web and on my Google TV, so it must be server based.
From the Plex web app, go to settings (wrench icon).
On the settings page, in the left menu panel scroll down to the manage section and then click on libraries.
After clicking libraries, the right panel will show your libraries. Hover over the library and it will show options that you can click on, one of which is “Manage Recommendations.”
Click that (should only be needed for movie libraries but you can go through for each library you have as there are multiple options) and one of the lines you’ll see is “Seasonal Movies.”
Uncheck the boxes for the different locations (probably all 3 for you) and then you won’t see those recommendations around the holidays.
