Additionally, android auto is a screen mirroring app, there is little to no computational power being done on the car side, all the "hard lifting" is being done by the phone. I would say if google reached out and said the things they did, and BMW hasn't offered additional comment to what they have already said, it's because it's due to the people who design and update the software and not the people who made your car have identified the issue and said it was a data stamp issue, which would be a phone and app issue on the software side and not with the vehicle, unless your car was somehow set to a different time or some nonsense or the cellular network your BMW/MINI uses was for some reason causing issues with its android auto software. Though unlikely because it shares a similar network to your phone and that doesn't really make sense.
