Sorry for the late response, and thanks for confirming what fixed it for you. It works for me on both my 3 and my wifes Y, as long as I make sure I have the appropriate car selected in the app first before I send.
I think this stuff is just "part of the tesla experience (tm) " lol. There are always going to be little glitches, etc, I think its just part of the ownership experience. For example (just as an example, I am not complaining about it), the last couple of days, my model 3 has defaulted to my wifes profile.
She hasnt driven the model 3 even a single time since March of this year, when we got her Model Y. I got in my 3 today, and after the seat tried to crunch me (Im 6'3 my wife is 5'6), I saw it was on her profile for some reason. She was not riding with me, in the garage, etc. My model 3 had her phone key set a priority as well, and mine has been the priority phone / key in my model 3 since "priority" device became a thing.
I set it back to my profile, set my phone back to priority, put my sunglasses on, and pulled on out to run the errands I was going to run. Just part of the "experience"
