Plexamp casting doesn't include album art

[ja2025]

Has anyone been able to cast to a WiiM device using Google Chromecast from Plexamp (also Plex from pc) and also have the album art display? I've tried it on my Ultra, Sound and WiiM Pro and it doesn't work, both on the displays (for the ultra and sound) and also the WiiM home app and home TV apps. It seems to be a Wiim issue in the way it works with Plexamp because I've tried casting to an Nvidia Shield from Plexamp and the artwork displays. Also tested using other music apps and Google casting to my Wiims does display album art.
