I am using Deezer with BluOs (Bluesound Node 2 player) and at an other location I use MusicCast with a Yamaha receiver.
Deezer works perfectly with BluOs, never any issues.
But with MusicCast there is quite often something wrong. Slow loading of new songs, flow interruptions, login keeps hanging, library does not load, etc.
I did not get any kind of useful response from the MusicCast helpdesk; is there any chance to improve the stability of Deezer in MusicCast?
