I'm no longer able to unlock my car, open the trunk/frunk, start the car etc. from new App on my 2020 MX. The app shows the animation that it is functioning, but the car doesn't respond. Anyone else having this issue?

I had a similar issue this morning where the car would not unlock. I put the phone in flight mode and took it out of flight mode and it still took about 1 minute before it worked. Traditionally putting the phone into and out of flight mode fixed it instantly.

I had this issue with my model s. Tech had to upload a new security certificate to get it to work again. Basically everything works except anything that is security related, opening doors starting the car etc. Funny thing is even someone worked. Just nothing to let me actually get in and drive the car!

Not sure if it's related or not but I just had my MCU2 upgrade.
