Can’t use the app to make my phone the key. Unfortunate in 2026

Can’t use phone as a key

I can’t use my phone or app as a key to start the car without the fob, even though it clearly states that you can and even add it to your wallet. I updated the app, the software in the car, spoke to an onstar specialist and even she didn’t know. I have an iPhone 16 pro, so the phone isn’t the issue. I really don’t enjoy carrying this huge key around. I’m kind of missing my Tesla now
