Is T-Mobile being really slow about rolling out Android updates to Pixel 6 phones?

Hi, thanks for checking in.  I've done factory resets a number of times with T-Mobile support.  Looking back, I'm wondering why that was recommended given that the latest T-Mobile version of software and security updates are from November 5th and that's what I have.  So I actually seem to have the latest T-Mobile released versions of Android 12 (Build SD1A.210817.036.A8) and Security (Android security update: November 5,2021).  I get a message from Google telling me to Update this device because I am at risk.  But T-Mobile's last update was over 90 days ago.  Not getting updates with a new flagship phone is disturbing.  I don't want to do a flash update.

Normally I would have given the same advice as you did because a factory reset would seem to be a way to force things.  But there's nothing to force.  One of those, "When you get there there's no there there" situations.  It took a lot of research to understand this because all the online articles such as androidpolice.com or 9to5android.com or others talk about how updates are working out for everyone but they must be referring to other carriers.  I'd really like to be wrong about this and find out I'm doing something wrong.

I do thank you a lot for checking in.  I think it's terrific that people like you do so.  ¡Gracias!
