Cover Art or lack off

[LI HUI]

I have an Element X VA03SE20356. I can never get any library cover art. I have upgraded the firmware to what it says "Is up to Date" and also the latest android version on my tablet.
Cover Art is supplied with the down loads usually in the format "Album Name" .jpg. This resides on the SSD's plugged into the USB ports. They are in the the folder where the music file is kept. The music file will play but there is no Cover Art displayed. I have followed the online tutorial and changed some of the file names to "folder" or "Cover". Still nothing. 
Is this a bug or do I need to do something else? 
I subscribe to Qobuz and always get cover art showing.
