Plex offline music loses artwork

Issue description:

Hi,
I’ve got Symfonium linked to Plex and all of my library is downloaded to my phone for offline playback.
I’ve noticed a few times now that after a day or so of not running a library sync, the album artwork disappears.
I enabled the option to download permanent image cache on the config page for the provider but it’s happened again today. I enabled debug mode but I’m not sure if it’ll help as I don’t know at what point the artwork disappears.

You have not enabled persistent image cache and your OS or some external “Optimizer” apps delete the files.

Ah I’d missed the image cache setting in the ‘offline cache and download’ menu. I thought setting the option to download the images under ‘manage media providers’ was the option.

Many thanks.
