Issues pairing with Apple CarPlay


Lately I have been having my children walk to school. On some occasions, I follow 10 minutes later to bring instruments or heavy backpacks as they’re arriving to school. On these days I’ve noticed that we can be talking fine on the Relay, but as soon as I get in the car, it glitches and seems to try to connect to my Apple Carplay unsuccessfully. Because my phone is paired with the car, I guess it sees the Relay App as a type of call, but no sound comes out of the car or the device for a while, even though I can see in the app that someone is speaking. Eventually if I have the radio on, I will get messages from my kids playing through the car speakers, but there is a 1-2 minute lag time before this happens. Can anyone help me solve this one?
