Since around 11/2021, I'm having intermittent issues with my navigation not auto-zooming on the main screen, nor showing the blue line there. I still get directions on the smaller screen. Had the chip replaced, MCU 1, version 2020.48.37.8. Any thoughts about what could be wrong? Tesla reset it remotely, but it happened again... Resetting (brake, both rollers) helps for about 1-3 weeks.
