Artwork not showing since transfer from NAS to SSD [Resolved - Cleared image cache]

Getting to grips with Roon nicely using Rock on a NUC.

Having installed my 1tb SSD internally to the NUC I’ve copied the music directories over to the SSD from my old NAS. Thereafter shutdown my NAS to check library access.

I can play from my new library but I’m missing album artwork? Can roon sort this or do I need to copy stuff over? Is there a quick and easy way to do this?
