How to add the app on Facebook again

You may need to re-add the app in cases when you get the rights to a page or a group after granting the rights to the app, for example:

1. You gave necessary permissions to the app earlier but you have just been granted access to a page or a group.

2. You gave necessary permissions to the app earlier but you have just created a page or a group.

To add an app again you should do the following steps:

1. Unlink the app from Facebook.
   To do that, go to the Facebook settings.
   
   
   Select the app in the “Business Integrations” section and press Remove.
   
2. Link a page or a group following the instructions in the related section.
