Also have issue 2014 P85D
Cannot unlock, start, frunk, or trunk - but everything else works fine
This is a recent issue, wonder if it has to do with update couple weeks ago
Something I noticed, when I do frunk the pop up comes up and I click yes, then the car graphic shows the frunk open for a little while, even though nothing happens at the car.
Other car (wife's) on the app works fine for everything - no issues
