I just got my 2017 X out of SC after chip replacement, however now I can not unlock the car using the tesla app. I can adjust the climate and open the charging port and honk the horn. However, when I try to unlock the car, it shows the lock open on my Iphone screen, but the car door remains locked. I can not unlock any door. I have tried deleting the app, reloading it, diconnecting my phone from the car's bluetooth and reconnecting it. Any ideas?
