My vote is because of cellular coverage. WiFi updates seem to be a myth at this point.
My vote is because of cellular coverage. WiFi updates seem to be a myth at this point.I tried manually and via scheduled updates three days in a row. Plugged in and connected to WiFi in the garage. The update kept failing. Then today I tried to manually update after parking at work and it uploaded via cellular. I tried driving the block a few times as Coral suggested to ensure the 12v was at a high charge. Not sure if the success was because of a longer commute, cellular instead of WiFi, or just dumb luck.
