Android 12 isn't all that much different or better, a security update for 11 would be good though. Nokia did the same with my phone though (Nov 21 update) and then it jumped to Android 12 Dec 2021 build with January 2022 Security patch for Google Play this week. So maybe the same will happen for your Samsung Note? Apparently what holds the releases up is certification by UK authorities and the phone networks even when the phones are unlocked retail models.
