Hey Charlotte and Luke,
Thank you for reaching out to us!
I’ve ran a test and disconnected the Facebook Token from my own local install and reconnected again: everything is working as expected, I couldn’t reproduce the issue you are experiencing from here.
To get started, could you please make sure that you are not trying to connect to Facebook while having a Privacy Badger extension enabled in your browser?
Also, could you please let us know what happens when you try to connect to Facebook using an incognito window?
Thanks!
Patricia
