When trying to switch from developer to live mode, developer.facebook.com
gave me this warning:
Before switching to live mode, you must provide both a valid Privacy Policy URL and data deletion information. Update this information in Basic Settings on App Dashboard
I have provided my Privacy policy url, but I dont know what to put here:
To be honest, I dont need this for live app, just for fb login on my test app, but when I try to login with Facebook, I got the error This app is still in development mode
. Ok fb, I know...
Fixed by putting the same URL as it's in a Privacy Policy field.
However, this should not be the right fix. But the app was made for testing purposes only.
