For better or worst, the latest Instagram update brings a new “Show Activity Status” feature which you’d normally find on chat apps. Accounts that you follow or anyone you message will now be able to see when you were last active on Instagram.
Show Activity Status is turned on by default. If you have privacy concern about broadcasting when exactly you’re using Instagram, you might want to switch it off.
Open the Instagram app, go to the Account tab, and tap on the Settings icon next to the “Edit Profile” button.
Scroll down to look for “Show Activity Status” and tap to switch off the settings.
With this feature disabled, you also won’t be able to see the activity status of other people.
