While new features can sometimes be a good thing, not all are welcome by users.
The Instagram Direct messaging component now shows if you’re currently active on the app, or when you were last active. This is very similar or equivalent to WhatsApp’s ‘last seen’.
The good news?
You can turn it off. In Settings, use the toggle to turn off the “Show Activity Status”.
This should really be an opt-in feature instead of being enabled by default. It is easier to stalk a person now with this feature and could eventually lead to bigger privacy issues.
