AT&T updated my Canadian phone with it's build of Android.

I fully admit that I did not pay attention when it happened, so I am to blame as much as them, but AT&T updated my _already_ updated to Android 14 Pixel 6, unlocked, Rogers Esim, roaming on AT&T, to what seems to be their build of Android 14 (UP1A.231005.007.A1).
Again, I should have caught it, but I'm just putting it out there that AT&T did this so others can may be more awake than I was.

It's a Pixel! All of the Canada and US models are exactly the same hardware. When you are roaming, the carrier is different and the system might have chosen that update for better compatibility. When you are back on Rogers, the next update will return to the Canadian OS build.
