Note: I don’t know how long this has been going on, but I think I really started noticing it early last year, but my memory fails me.
Introduction
As the title suggest, Plex uploaded seasonal posters are reverting after a metadata refresh.
How to replicate:
Edit a season in Plex
Upload your custom poster
Save
Refresh metadata
Issue
Explanation
Seasonal posters are reverted during a metadata refresh, but the series poster is not.
Cause
When uploading a Series poster, it selects your image after the upload, so when you save it, it actually saves.
When uploading a Seasonal poster, it does not select your image after the upload, but it changes the image on entry, giving the illusion of it saving correctly, until you refresh metadata; then it reverts back.
End notes
I did some multiple tests on my own and this is a consistent issue and whenever I select the Seasonal poster manually efter upload, it doesn’t get reverted with a metadata refresh.
So should be a relatively easy fix (maybe I jinxed it now), something along the line must have broken the auto selection for seasonal posters, which is why this has become an issue.
While not a solution to your problem but have you considered using local posters? I moved approx a year ago to use local assets (show, poster and fanart) for everything in my library.
While a bit of up front work it will 100% give you control of the artwork used in your libraries.
What I do right now for my “flow” is uploading my own images through the panel, then I refresh the series metadata since I use Lambda (from ZeroQI) which allows me to automatically export stuff like that to being properly locally saved.
This (last I checked) also compressed and renamed etc the images for me, so I do sort of use local – just in a roundabout sort of way
I used these kind of posters and selected them for the seasons of my test show.
After refreshing Metadata of the whole show, the season posters remain selected.
Yes I do for some, but for new entries I start off with not having any local assets.
This again seem to occur because the browser doesn’t auto select a poster after upload.
If I select the poster after upload in the Client GUI, then it successfully saves and uses it. It’s unselected after upload by default (for me)
