FLAC Artwork not showing up on M1 Clic

Hi Guys

I recently purchased an M1 Clic and have started ripping all my CDs as flac files onto a synology NAS.  I am using XLD to rip the CDs and also Blisshq to keep my library organised and to add artwork. I do this by embedding into the file and also putting a copy of the artwork file in the corresponding albums folder.

My problem is that whenever I play a track through the M1 Clic it doesn't show the artwork...I know it is there though as I have opened the files on mt Mac using the Decibel music player and they show up just fine...confused...

Any help greatly appreciated!

Nick
