I am migrating our Auth0 Facebook connection to a new app. The connection against the new app was working until recently. Now when I try to perform a Facebook login or test the connection whilst using the new app the below error is returned
If I revert the connection back to use the old Facebook app credentials the connection and logins work fine.
If anyone has experienced this before I’d be keen to hear from you. Otherwise I may need to try creating another Facebook app from scratch and see if that makes a difference.
