Instagram is finally working on a feature that its competitors have had for some time: disappearing messages.

Jane Manchun Wong, a researcher who specializes in reverse engineering apps, was the first to discover the feature.

Instagram is working on “🙊 mode” where messages disappear

It seems to be in an early barebone version but I tried my best to demonstrate how it might work

Wong reached out to Instagram and they confirmed it was a feature they were working on, but that it had not yet reached external testing.

We’re always exploring new features to improve your messaging experience. This feature is still in early development and not testing externally just yet!

Given Snapchat’s success, it’s a safe bet this feature will be extremely popular once Instagram rolls it out.
