Hey guys. I have also been dealing with this problem. To make it even more complex, I am the primary driver of our model three.
However, I don’t get any push notifications on my iPhone, however my wife gets all of them. We literally have the same settings in our Tesla app as well as in our iPhone settings. We recently had mobile service performed and she would have to let me know whenever there was a message that came in or whenever there is an update for the car.
I'm in the exact same situation as you. Primary driver and not getting any alerts on my Android. Secondary driver that has Android as well, is getting all the alerts.
Settings are identical between both phones and I've done all the basic troubleshooting..
Have you heard back or figured out anything?
