Hi @geekrawker! Thanks for posting to community.
To clarify, is this happening when connected to Android Auto in your vehicle or when listening on your Android devices - this thread is specific to Android Auto.
I do see that you've written into our User Support team via email. If you continue to have trouble, feel free to respond directly to their email for further help or any questions you may have. I would recommend including the date and time you received the message so that they can take a closer look.
Keep in mind that it's possible that the simultaneous streams warning was tripped on accident, which may happen from time to time when switching from one device to another. If that's what happened, you can go ahead and disregard that message.
