Facebook’s troubles continue as the company has just announced that the platform experienced a “bug” that set the audience for tens of millions of people’s posts to “public” even if they had set their privacy settings to share them with a smaller audience. This bug affects posts shared between May 18 and May 22. However, it appears that the company didn’t change the settings back to what the users had set until May 27.

The bug apparently happened because Facebook was building a new “featured items” option that highlights content on profiles. These items are visible to the public, however, the company extended that setting to all the new posts, TechCrunch reports. Seems like another side effect of the company’s now-publicly-discarded “move fast, break things” motto.
