Hi @Julien_Monguillot ----- Thank you for the report and sharing this observation with us. The feedback is always appreciated.
Moving forward, having some details about your setup (as seen here) would be very appreciated, as this will give us an idea of what you are currently working with 
Furthermore, in regard to this behavior you are experiencing. If you haven’t done so already, I would recommend trying the following:
-
Power cycling your equipment, networking hardware included (i.e router, switches, etc).
-
Clearing your TIDAL cache.
-
Log in and out of TIDAL within Roon.
