My cellular connection in my model 3 disappeared on me around noontime today while driving, and hasn't come back for the past few hours. Cell phone (which is also ATT) is working fine. Just wondering if anyone else is having issues or if it's something specific to my car. The signal bars aren't even on my screen anymore (vs. being greyed out). Have done the soft and hard reboots of the MCU, and powered the car down for > 5 mins with no effect.
