My Messenger app is blocked even though I did not select it

In some cases, when you block Facebook through the app picker (instead of manually adding it as a website via Safari URL), AppBlock may also block the Messenger app due to a recognized connection between the two.

This typically happens when “facebook.com” or “m.facebook.com” is blocked in the app picker, causing Messenger to be blocked as well. To avoid this issue, we recommend unselecting all Facebook-related websites in the app picker and instead blocking them through the websites picker.

This method should prevent Messenger from being blocked while still allowing you to block Facebook.
