I have a 2016 Mustang and a Samsung phone. When I launch the Spotify app from the APPS menu, it will get stuck at "Loading ..."
It shows the reverse, play and forward buttons on the SYNC 3 screen, but that's it. If you hit the MENU button, and select something like Your Favorites, it just goes back to Loading.
The only way to get out of this is to shut the car off, then back on - then (sometimes) Spotify will work correctly.
I've also restarted the phone when it does this, thinking that would help -- no dice, SYNC 3 is literally hosed at this point.
For what it's worth, I thought it might be my phone so I tried it with an iPhone. Same thing.
When Spotify does work, it seems like I can only advance or reverse about 4 or 5 songs. Then the only way to advance or reverse is to hit the Play/Pause button, then it will start working again for another 4 to 5 songs.
I have a Spotify premium subscription so I don't know if that's limiting me on the track skipping?
Is it just my system?
