I apologize for the lengthy post, but just curious if anyone is having the same issues with a so-called "known issue". I updated to 2018.12 on 3/28 or 3/29 on MCU2 (2nd week I've had my MX). At some point over Easter weekend, I lost network connection with the iPhone app. I called to report it and was told that the car had not sent any data to Tesla in several days, but they figured I hadn't been driving or it was parked in a remote garage, none of which was the case. I spoke with my SC and they scheduled a loaner MS so they could hard-wire an update to my MX. About 15 minutes after scheduling the loaner, my SC called me back and said they got a call from Freemont stating this was a known issue with the MX and a fix would be out soon. Fast forward to today- I called to get an update on this "fix" and after explaining the whole thing again, I was told it has been escalated to engineering...again. I have tried rebooting via the scroll wheels - nothing. I tried the complete power down via E-brake screen - nothing. Most of the time I can't reboot when pressing the brake pedal, I have to open the door for anything to happen. I've seen the multiple posts about rebooting via different methods, but is anyone having any app connectivity issues?
