Spent an hour trying to add the Digital Key to the wallet app for my new Pixel Watch 3 paired to Pixel 8 Pro. Called support and opened the ticket. They called me back and informed me feature is not available yet it is on hold for now. Will try again after the next update.
Have not charged at a DCFC yet. 3 months, 6k miles. Will need to do it soon before the 7500 service. Gen 2 Dual standard T. I did notice however, that charging slows down at 93% to 7.1kw from 11kw on the garage L2 Rivian charger since the .43 update few weeks ago.
Would be interesting to know is the issue persists at a Level 2 charger in a different location (not in your home). Maybe try a Riivian public level 2 charger?
