When the Bark Home is connected to your router, it filters apps and sites on devices connected to your home Wi-Fi. Some Samsung devices using Secure Wi-Fi may show this alert as a result: "Suspicious activity has been detected on the current Wi-Fi network"
There's no need to worry. Bark Home is a trusted network filtering service. Tap Add to exceptions to dismiss the alert. Samsung Secure Wi-Fi will still alert you about suspicious activity on other networks.
