I tried out the built-in Deezer app on my V1 yesterday - the result is exactly like with my Avant....laggy, slow, unuseable.
Both tv’s are wired and internet speed is far more than enough here.
Honestly, I can’t see what has changed - and I am rather confused that some people tell, that the app is working well at their places.
Besides - there has not been any updates for the V1/BV11/Avant 1st gen platform for ages!
