The Instagram For You page (explore or suggested content) can reset due to changes in your interests, one-off interactions skewing the algorithm, or possible account activity from others. Instagram continuously updates its algorithm based on your behavior, search history, and followed accounts, so shifts in any of these can cause the page to refresh with new content types. Sometimes, it might be a temporary bug or a result of Instagram testing new algorithm features. To address or control this, you can clear your search history, unfollow irrelevant accounts, and use Instagram's new option to reset suggested content in Explore, Reels, and Feed to get a fresh start tailored to your current preferences. If someone else accessed your account and engaged with different content, that might also influence this reset. Occasionally, the reset resolves itself over time without user action. Instagram is also testing an official way to reset content recommendations, which can help get back to more relevant posts based on your updated interests.
