Days after the company unveiled Fleets, its new Instagram Stories-like posts that are theoretically supposed to disappear after 24 hours, a bug has basically made them pretty useless.

According to TechCrunch, Twitter users disclosed the bug, which allows others to view Fleets on public accounts past their 24-hour expiration date, on Saturday.

Apparently, the bug appears to be related to a developer app that could scrape tweets from public accounts using Twitter’s API, the Verge reported.

The company told the outlet that the API doesn’t return URLs for Fleets that are older than 24 hours, adding that once it fixes the issue, people will not be able access Fleets after they expire even if they have a URL for an active fleet.

On its end, Twitter does keep a copy of all sent Fleets after they expire or are deleted by users in order to take enforcement actions against content that violates its rules.
