Trouble Turning On Master Switch
If your Master Switch won't turn on, this is because your account balance is negative. Your Master Switch automatically turns off when your account balance is negative. Navigate to the Billing page located in the left hand menu, and fund your account balance in the My Funds section. Regardless of having an active subscription and credits remaining, your account balance always needs to be in the positive. Here is more information regarding Ringy billing:
