I'm having same issues as you (Android 5.0x) in my Challenger. At least the bugs are consistent cross platform (both iPhone and Android). I haven't spent too much time figuring it out yet since I'm not using the car.I'm having issues in the Charger with ViaMobile. Phone is paired, app is installed. When I click to start Pandora, it says to launch the UCONNECT app (which is already launched) and then says to pair my phone (which is already done). We tried deleting/re-adding phone and app, and tsc even tried logging into his and it still didn't work (even though it works in his Challenger).
Any suggestions?
