Short version: Facebook sucks, and we’ll have to jump through some hoops if you want to continue using the Social Media Wizard app.
Longer version: Facebook has decided I’m not a “Tech Partner,” and therefore they have restricted the Social Media Wizard app. (Why am I not qualified to be a Tech Partner? Don’t know! What even are the qualifications of a Tech Partner? Don’t know! Why does Facebook hate me? Don’t know!)
I’m trying to resolve this. However, they won’t provide any reason why they made this decision, and I have no way to reach an actual human being to learn anything. So, I’m not optimistic for a quick resolution.
Workaround: If I add you as a “test user” of the app, you should be able to continue using it. If you’d like to do this, just contact me and let me know your Facebook Username or ID. (Info on finding your Username: https://www.facebook.com/help/211813265517027) I’ll invite you to be a test user. I believe you’ll receive a notification from FB and need to accept the invitation. Then you should regain access to full functionality.
I'm really sorry for the trouble, and am working to get this resolved.
