As much as this is a bummer, 5 years of updates is still pretty good IMO.
I don't care really honestly about software updates, as for me, they usually bring unwanted and unnecessary changes. I care more about security updates.

Could the quarterly updates have started for the S21 series?

Today is the last day of March and there is no sign of the March security update although the S22 series has received their update.

Might this signal just 3 more security updates for the S21's before they are abandoned by Samsung?
