Playlists and Artists Slow to load on Android Auto platform

I recently got a new Honda CR-V that supports Android Auto. At first I couldn’t get Plex to show as a music app which was easily solved by enabling “Unknown Sources” in Developer mode. Now when I choose a playlist though Android Auto, it shows a spinning circle which pauses after a few seconds. I’m guessing I have too many entries in my playlist? Is there a way to speed this up?

Thanks

Updating to the newest version of Android Auto on my phone solved the problem.
