App no longer works for me – Who Unfriended Me - Facebook Friend Blocker & Deleted Social Media Edition FREE Review

I love this app it's been very helpful. But recently it hasn't been working. It'll say I can no longer log in through Facebook that it's in a testing and I need to contact testing admin. So now the app is useless since it working on me.
