I have been using my tesla app without a problem for about 6 months. Everything on it works except for the ability to drive without the key. For whatever reason, tesla could never get this function working. Now for the past few months, I can no longer unlock the car with the app. It will lock, control the AC, honk, flash lights. Summon is intermittently working... I have tried resetting the car, new firmware, deleting the app, logging in and out, resetting password. The same is true on my wife's phone as well so its not just my phone. Tesla is working on it, but noone has had an answer. Anyone else with similar experience?
