I’ve been using iOS beta 3 for a few days, and I’ve began to notice that I am not able to send messages through CarPlay. At first, I thought it was a bug with my phone, so I restarted it. Then, I removed my car from CarPlay and reconnected, then connected it to a family members car and still have the same issues. The issue being whenever I try to send a message using Siri, she replies with “There is not an app for that, download one when not in the car.” Or something along those lines. If anyone else is having the same issue, or knows a fix, please let me know.
