Android Auto receives, but won't send SMs while driving

[J H6]

I had an S7 and upgraded to an S10e recently. I have not been able to get Android auto to send SMS messages. It will receive them but it won't send.

I have uninstalled and reinstalled Android Auto twice and gone through various settings. I can say Send Text Message and it will ask "who do you want to text?". I respond with a name and nothing.

My S7 worked great with Android Auto.

Any suggestions?
