I'm pretty fed up with my AP2 randomly deciding not to work. The last week or so, it hasn't worked in the morning at all. Maybe if we pool our experiences, we can figure out what the hell Tesla is up to. OTOH, it seems to consistently work on my commute home. In my case, I figure it could be due to temperature or poor LTE at home (but good wifi), but it may be unrelated to my specific situation (for example, if Tesla is uploading a update, and my morning commute catches it midway, and their upgrade mechanism sucks).
