Kurt just joined Facebook. Leo says it's a love hate relationship. You can reconnect with friends and family, but it's an annoying time suck. But Kurt is getting pushed by Facebook to post an image on his profile. Leo says that Facebook is doing that because they are trying to stop fake accounts. So he uploaded one and now he can't log in! Leo says that Facebook takes the time to verify users before they can re-login. It could take up to 72 hours. Facebook has an explanation of this on facebook.com here.
Leo says to be careful what permissions he gives to Facebook. He should be reluctant if he gets requests for Face ID or his social.
