????

I have the same problem with an m10v2 but different error code "Upgrade required Deezer: xxx xxx 418". but only with different artists and titles.

I have the same issue. Happening on about 20% of tracks when using Bluos. Never had an issue before. It needs sorting ASAP

same issue on nad m66 with deezer only.. all bills are payed but deezer service lacks. do anyone from support read here or is it 127.0.0.1

btw,.. on random tracks an on several deezer radio station too

​@Jaime.Deezer Could you please take a look at this and/or pass this to the developers? 

Same issue here...i have reported this as well in the bluesound community : https://support1.bluesound.com/hc/en-us/community/posts/28168609313431-Upgrade-required-Deezer

J'ai le même souci. Obligé de connecter mes diffuseurs Bluesound Flex 2i via Bluetooth pour contourner le problème de l'application Bluos en passant directement par l'application Deezer. Pas normal. Faut-il arrêter l'abonnement Deezer pour aller sur un service de streaming plus fiable ?

Hab auch das Problem. Streame zzt über Bluetooth. Der Fehler tritt, wie bei anderen nur bei bestimmten Alben auf. 

...and you are not using bluesound?

I use node 130n. When i connect with Bluetooth, all is ok. When I use Bluos the error occurs
