I used this all the time on my S8 but now with my S21 I am having issues. Sometimes the screen on the car won't load but most importantly it won't tell that new texts have arrived. I checked all the setting and removed the car from AA and re-added and it still won't notify me that new texts are available. I have tried a different car with AA and I have removed the app and reinstalled. I have to look at the phone to see that new ones have come in. I opened up a new topic and it was closed.
