I am using latest beta-version 2.8.1, but I had this issue as well with version 2.7.3 :
I enabled „Sonos“ INTEGRATION 0.4.1 and created entities based on this Integration.
Yesterday the device was shown incl. an icon in the device-list. In the device-list the cover-image of the song being played was shown. Today it is empty, even not the entity-image is shown:
How can I get the icon reliably shown? It will be nice showing the song-cover, when a song is being played. If no song is being played, the device-image should be shown.
Any idea about how to get this fixed?
A restart of Remote3 wasn‘t helping.
