Today I was at columbus Ohio Rivian facility. Reported to them that i could not get Alexa volume very loud, or even loud enough to hear and understand .They are now aware of the issue and think somehow the latest update is the culprit. Hopefully it will be fixed soon in a future update.
I use discount tires for my model y. Still waiting on my R 1 T. Better mileage for my Hankook tires than the ones from Tesla. They did have pucks for model y but I know Rivians require longer pucks.
