Half-swiping on Instagram messages is a feature that allows users to archive a message thread without fully deleting it. This can be useful for decluttering your inbox or hiding messages from specific users without having to block them.
To half-swipe a message thread, simply swipe it to the left (on iOS) or right (on Android) and tap the “Archive” button. The message thread will then be moved to your archive, where it will remain hidden from your inbox until you choose to unarchive it.
