I know. I agree. But this dip or loss of TuneIn or Slacker has been going on since the beginning. Its not limited to MCU1 or MCU2. I can say that now that I have had both. I bought my first S in 2013, and my third in 2017. All three cars have lost streaming signal when switching from home WiFi to LTE. And still occurs since March with MCU2. Nothing new. However, on all three with MCU1, I had to switch stations, channels or source, to get any sound to come back after WiFi was out of range and LTE was supposed to be up. Now - with different WiFi card in MCU2, I lose signal, but it comes back on its own after a delay of 15+-30 seconds. Don't like it, but an improvement.It turned out to be not as big of an issue as I had feared going in for the upgrade because TuneIn filled in fine. But still inferior to FM radio in that it is interrupted about 3 times on the drive from my house to work each day (due to wifi to LTE switching and spotty cell signals).
