Facebook migration: Will I be able to revoke the authorization?
Yes, you always have control over your Facebook page. 👍
If you want to revoke this authorization, you can follow these steps on your Facebook profile.
Click on “settings” → "Business Integrations" → "Smiirl" → "view and edit" → then remove the “Manage your Pages” button.
To have more information about it, you can have a look at the Facebook documentation.
Note that, by doing so, you will get back to the old software version so the reactivity of your Counter won't be so good.
