Installed 2021.4.18 in our 2018 Model 3 this morning, rebooted afterwards as usual. Since then, the map is zoomed out quite a bit and doesn't auto zoom as it used to (not using navigation). You can manually zoom in and it will stay zoomed in, but on the next drive it's zoomed out again. The previous update was 2021.4.15.12.
Anyone else seeing this? Our 2018 Model S has the same build, but I don't see this issue there.
I was going to create a new thread for this rather than burying a response here, but let's see how this goes.
