Images of root Album Folders in the library

Hi, I’m using Volumio 3 on my PI 4 based DIY streamer.

Why doesn’t the cover image appear in some folders in the music library root? If instead I open the folder, Volumio shows me the correct image for each track. The images are all and always in jpg format.

I also tried inserting other images manually in the folders, but the problem persists.

Thanks

Have you reset the Album cache after you’ve added new pictures?

Yes,
Now, It’s seems to accept the image or a new image changed, just if I edit the name of the folder before a new update/scan library…
