For now, however, I have never written on the subject. Since the last (forced) update of TuneIn I have problems with a whole series of stations. Most of all, this only bothers me with the message “Invalid medium”. But also WDR2 is affected. NDR2 is currently running, but was also partially affected. I don’t have a VOC but an external Huwai modem as a WLAN hotspot. If I use this as a hotspot for my mobile phone n There I can stream SWR3 over the mobile app. So it is definitely a problem of the Volvo APP. I have already removed the app on the Volvo and installed it the next day. An installation error is therefore also unlikely. Since I have not found anything on the net to this problem yet, I would be interested if others get this error message or if this is an isolated problem with me.
