I’m sorry to report we have found an issue with the Facebook sign-in feature of the app. We will no longer support the sign up or sign in feature with Facebook. If you have experienced a “loading” screen, please contact [email protected] or [email protected] and we will reset your account. You can also “Sign-up” at the bottom of the GUNTRACK app homepage and use your email and password to sign-up. Sorry for the inconvenience.
