The phrase indicates that a user’s most recent activity on the Instagram platform occurred within the preceding 24 to 48-hour period. It is a timestamp reflecting when they were last using the app, sending messages, posting content, or otherwise engaging with the platform. For instance, if a user views a profile and sees this indicator, it suggests the profile owner had been active on Instagram sometime yesterday.
This activity status provides valuable context regarding user engagement. Knowing a user was recently active can influence decisions to send a direct message, expecting a relatively prompt response. Historically, the availability of such activity indicators has fluctuated as platforms adjust privacy settings and user experience features. The information contributes to an understanding of user availability and potential responsiveness within the social network.
