There’s a new feature that’s on by default on Instagram, and you may or may not like it. It shows people you private message or tag in your Instagram Stories when the last time you were on the app. It’s apparently showing up for both Android and iOS users. If you would prefer to keep how often you are on the app, you can just scroll to the bottom of the settings menu and turn off the toggle beside the “Show Activity Status” option. If you do this though, you won’t be able to see when other people were last online.
