In addition to OS updates, there is the underlying Google Play system. This updates separately from the OS. I checked my tablet yesterday and found I was still on the June version (I think).
Settings > About Tablet > Software Information You'll see Google Play system update in the right panel. Tap on that and it will prompt you to restart for the update. My version after my update yesterday was November 1, 2022, but it told me just now there was ANOTHER one, but it has the same date.
