I wish it were weeks. On my AP2 MS, I've waited approximately two months between the last two updates I received, and even if the next one came tomorrow, it would be at 1.5 months. In two years, the longest I ever went was 63 days, but I'm expecting to break that record with the update from 2018.50.6 -- TeslaFi shows that about 75% of AP2 cars are still on that one.
