Level 32
Facebook has been slow to introduce support for Dark Mode to all of its apps, but it has made some progress since its introduction in iOS 13, with Facebook Lite, WhatsApp, Instagram, and Facebook Messenger apps for iOS and iPadOS all working with the iOS feature. While the main Facebook app has lagged behind with offering a Dark Mode to users, that is finally being addressed.

After the discovery by some users of the feature's availability, Facebook confirmed to SocialMediaToday on Friday that it is officially out, but it is only usable by "a small percentage of users globally right now." It seems that Facebook is slowly rolling the feature out, as it customarily does over several weeks, to ensure it continues to work without any major issues as more people gain access.
