Pretty sure I found a bug in the 2.7.0 update w/ AirPlay and the rest of the apps and navigation that depend on a 'cell signal'. I'm able to repeat it every time, and even after an 'A' reboot:
noticed that on the pilot display that shows your 'cell strength' was showing one tick mark (low signal)... i go to Tidal/Spotify and I can't get anything to play. Tidal was not even connecting.. just the spinning load graphic. Assumed it's the low cell strength. If I look at phone, it shows 5 bars and LTE.. i look back at the pilot screen... one bar. Hmmm.. so then I open carplay and on that display that shows signal strength, it matched what my phone indicated.. 5 bars, LTE. I then noticed as soon as the CarPLay screen appears, the signal strength on the pilot screen jumped to 5 bars.. then I go back to the Tidal/Navigation/etc, and it works.
I can repeat this EVERY time I can't get any of the audio apps to work (aside from FM), or even more fun.. if the nav system shows me the all too familiar 'can't get a network connection'. No matter where I am, driving or parked in areas of acceptable cell strength. If Tidal locked up, or Spotify vanishes (like it does about once a week), it's 100% cured if I open CarPLay, sync the cell strength, and then go back to fully functional Tidal/Spotify/Navigation.
Anyone else wanna verify this next time you're locked out of the apps that need cell network?
