I have regularly been getting "your device has stopped charging" and it'll always resume instantly, it's just annoying to get that notification. Tesla told me it's a known bug and a future update would fix it. It's not fixed after this update.
It's incredible, you'd think two pieces of official Tesla tech, car and charger, would work seamlessly or at least be a priority if they didn't and it was widely known.
Thankfully the car is still fast and very fun to drive and that was the main buying point. Seems tech is always gonna be tech eg buggy, troublesome, not perfect. For me the tech is 98% great, sure I'll moan about the 2% but overall happy.
I think sometimes we have high expectations for what is explicitly still in development and we are the crash test guinea pigs, so to speak.
