Instagram may be planning to fix this issue with a new "You're All Caught Up" feature that's designed to notify users when all unseen posts from the last 48 hours have been viewed.
The feature was first noticed by TechCrunch, and an Instagram spokesperson confirmed that it is being tested and will show up for a limited number of users.
Instagram did not, however, share details on how it works and whether it includes every single post from the people you follow or just the best ones that its algorithm has decided to display.
The new "You're All Caught Up" text is part of Instagram's pledge to offer a Usage Insights feature that will let users know just how much time they're spending in the Instagram app.
"We're building tools that will help the IG community know more about the time they spend on Instagram - any time should be positive and intentional. Understanding how time online impacts people is important, and it's the responsibility of all companies to be honest about this. We want to be part of the solution. I take that responsibility seriously," Instagram CEO Kevin Systrom wrote on Twitter last week.
