I suffered similarly but I think the latest software (>5.0) solved most of the issues and I don’t notice the software anymore at all (which I take as a positive - I.e., it just gets out of the way)

I'm not sure we're even on same versions. They appear to push different branches on different platform revisions.

Mine still cold boots/watchdogs every time you start the car in what I suspect a Patriot-style fix of numerous issues. It still has confirmation dialogs over confirmation dialogs (e.g. when selecting CarPlay you get to confirm your choice three times). Voice input is still unusable: the only thing it reliably recognizes is when I tell it to fuck off (and it scolds me for that). Door locks/keyless became more unreliable, which I frankly doubted was even possible. Everything is lagging, especially after cold boot: getting to entering nav destination after you sit in the car takes an eternity.
