What does the blue checkmark in Facebook Messenger mean?
Thank you for clarifying that for me, are there any other important features of Facebook Messenger that I should know about?
Well, Facebook Messenger also has a feature called "Messenger Day," which allows you to post photos and videos that disappear after 24 hours. You can also use Messenger to make voice and video calls, and even send money to friends and family.
