Artist poster blank/not finding for last added artists/albums

[mkatich]

Hi, I have done searching several times over the past few weeks and haven’t had any luck remedying this. The last 2 albums I added, different artists than were in the library before, did not gain any artist poster. I tried refreshing metadata for just the artists and for the whole library and that didn’t help retrieve a poster for those 2 artists (Santana and Little River Band).

Here are other threads I’ve read and some things I’ve tried-

The Plex Dance ™

The purpose of this is to remove all cached metadata and xml data for an item that Plex usually keeps. This helps when you want to “start from scratch” for particular item move all files for the media item out of the directory your Library is looking at, so Plex will not “see” it anymore scan the library library (to detect changes) empty trash clean bundles (in menu next to server name, when accessed under ‘More’) double check naming schema and move files back scan the library Support articl…

Posters and summary not downloading

I’m curious to know what firewall and anti virus you are using. You get a good match and it looks like Plex grabs information, but it gets messed up somehow.

Premium Music -- So much missing artwork

What can be done here?   MY NON Premium music library has ZERO missing artwork for like 120GB of tuneage...but this new one...not so much. I really don't feel like doing that all over again.    

Any help is appreciated. If you have any other methods for fixing, I’ll give it a shot.

I also tried adding an artist poster to one manually using a URL of an image at last.fm, but still nothing showed up (maybe because it was a .webp extension). Then I saved the image as a JPEG locally and used “choose an image” in Plex and that worked.

Server Version#: 4.39.1
Player Version#: web

UPDATE 2020-12-23
I switched my library’s Scanner from Plex Music Scanner to Plex Music and the Agent from Last.fm to Plex Music and then did a Refresh All Metadata on the library, and it actually refreshed the artists posters and added image for those that were missing posters! Woohoo! I swear I tried this before. AND… I actually have other posters showing up that I can choose when I click Edit on an artist. Wow, finally. I wonder what is wrong with the Last.fm choice.
