Can you still use the old Singapore dollar bills as legal tender?

As far as my knowledge goes, which cutoff date is set on February 2022, the old Singapore dollar bills are no longer legal tender. The Monetary Authority of Singapore (MAS) had announced that all old-design Singapore dollar banknotes will cease to be legal tender from 1 January 2021. Please note that this information might be outdated, so it's best to check the Monetary Authority of Singapore (MAS) website or a reliable, up-to-date source for the latest information.
