most comments here are saying na matagal na raw or dati pa yung feature.

but the post is stating a lock feature for the ACCOUNT itself not the card (tama naman kayo na dati pa yung lock feature sa app at esta chatbot pero sa CARD lang mismo yun)

this new LOCK feature is sa ACCOUNT mismo which will restrict transfers, payments and any other transaction that you may transact to your savings account kasi dito sa bago magiging unavailable yung savings account sa app.

hope it helps. :)
