My 2022 AGT was updated to 2.6.11 - my first OTA update since December (update to 2.6.0 happened when the car was in for annual service). I noticed the update available through the app. After acknowledging that the doors would remain locked during the update, it took a while for the download to start. I opened my garage door in case it relied on a cell connection for the update and the signal wasn't strong enough. Then it started updated. The car should be connected to my home WiFi ... wouldn't the update prefer to come over WiFi?
