I have seen a few reports saying that because the V9 update is very large, you have to be connected to WIFI on a consistent basis to get the update. Is this really true? If that's the case I'm going to be pretty frustrated because nowhere did Tesla make that explicitly known to their customers. I live in an apartment and my car doesn't have easy access to wifi. I would need to create a hotspot on my work phone but there is no way I am downloading that update on that.
