I am using a Galaxy S8 and Android Auto. I can't seem to see all of My Collections. I have cleared the cache with no luck. I can see them when just using the Pandora app, but when using Android Auto it only shows maybe 10 of my stations. It is missing any of the new collections I recently added.
I also when parked don't see any way to browse and add them so I can't find any way to get them to work with AA.
I too have this same issue. When using Pandora in Android Audio, only a portion of my stations show up. And not even the most recent listen too stations either. Just a random list of my stations. HELP!!! Ben
