Hello all. I have an Android tablet install in my Grand Cherokee. I'm using a PAC adapter and JoyCon EXR for steering wheel controls. Lately (as in the last week), I've been unable to change tracks, or pause and play. I suspected the PAC and JoyCon, but after further investigation, I found that the Media Utilities widget no longer allows control either. I am also unable to play/pause through a previously working Automagic profile (flow). What the heck could be going on here? It seems no 'external' control method for music works anymore. Everything works fine if you are in a specific app, like Slacker or Pandora for example. I'm at a loss. Thoughts?
