I had the same experience as peer comments. I'm on Pixel 8 and Google Fi. When I check for updates, I'm told I'm up-to-date with the last update being over a month old.

Not working for me on Android 16, additional taps of the "Check for update" button in the bottom-right don't change the fact that it says "Your system is up to date" and that the last change was last month.

I see same behavior on my 8.

Could be model-specific. I got the update by doing that manually on my Pixel 8 Pro, that also happens to be on the beta track so there are a few confounders. But that is the way to get the latest software that is waiting to be released to your phone, without waiting.

I don't see it yet either and have mashed it a bunch (Pixel 7, T-Mobile). Says it's running October's update with no updates available.

Thanks that worked, so weird that you have to do it twice...
