Having issues with Facebook's Messenger Kids app not loading on a device managed by Circle? Make sure you've set Facebook as an allowed app.
How do I allow Facebook's Messenger Kids app?
Messenger Kids app is dependent on Facebook's services to load. Since Facebook is blocked on some Filter levels you'll need to make sure the level is appropriate to load Facebook or set Facebook.com as "Allowed" using a Custom Filter. Particularly, Pre-K and Kid level filters won't allow Facebook to load by default (since that app requires users to be 13 years or older for use.)
