They had given me six days to add a Privacy Policy button into my app (my website has it, and my app's metadata has it, but apparently they require a button in the app UI itself, which I didn't have).
I told them I would add it, but I needed more time, as getting an app update out with only 6 days notice the week before Christmas is impossible (I have 5 apps that use Facebook login across 3 app stores, iOS/Android/Amazon).
They told me I could request an extension, which I did do multiple times, but the extension was not granted.
Joking aside, sorry this happened to you. These kind of inhumane policy do nothing but create stress.
The solution to a completely avoidable problem. Anyone who interacts with facebook these days, whether as a customer or as a mark, deserves whatever befalls them.
