Okay guys.... I was on the phone with UConnect tech support... After the update it will take some time for the apps to show up automatically. (for me it was mayne 10-15 mins).
However, once they showed up I was getting a subscription error.
Tech support had me log in and out of the app on my phone, that did not work (but she said for some people it did work)
On the app (for iphone at least) there is a green light in the via mobile part of the app. When the app is connected correctly its green, when its communicating it turns blue, if you see a red light its bad.
In the end to get it to work, I had to go into the uconnect store app. Go to the My Apps button, then remove and re install apps. This worked and corrected my problems. Basically it cleared out all apps, re installed and refreshed the subscription information on the radio.
Its a pretty cool feature set to say the least. I only tried the IHeartRadio, and it was a nice interface. I will have to play around with it more to see how all the apps work.
