->There are some nuances in manual adding domains. For example, if you manually exclude the domain `yahoo.com`, all `*.yahoo.com` subdomains will also be listed in exclusions. However, domain names with other top-level domains, such as `yahoo.jp` or `yahoo.fr`, will not be excluded. Or you can add `youtube.com` to the exclusions, but the domain of the same service `youtu.be` will not get into the list. In this case, it’s more safe to use built-in lists of services, because we put there all subdomains related to each platform.

 As you can enable subdomains in service lists, we added boxes that reflect the status of each service — you can see them on the main screen of *Exclusions* to the left of each service name: **fully-enabled** status is marked with a white check mark on green background, **fully-disabled** — with a gray box, and **partly-enabled**, which means that one or more parameters were changed — with a green square on white background. Good news: you can always return to the default view of service lists in case you’ve deleted or disabled any domains from there.

 *Operating mode* section allows you to choose one of three options: VPN, Proxy, and Compatibility mode. In *VPN mode* all traffic is routed through AdGuard VPN automatically. When the *Proxy mode* (SOCKS5) is on, AdGuard VPN runs a local proxy server which can be used by other apps to route their traffic through it. Choose this option only if you know what you are doing. Enabled *Compatibility mode* allows AdGuard VPN and AdGuard Ad Blocker to work together.

 The next two sections are *Logging level* and *Diagnostic info*. Concerning the first option, it is not recommended to enable the Extended or Extreme logging level unless requested by our support team. Diagnostic info, locally stored technical information about the device and connections (IP address, ID, ping, etc.), can be sent to us in case of any technical problems.
 
 The last section of *Advanced settings* is *Low-level settings*. We urge you not to enter this section unless you are highly qualified or have been asked to do so by our support team. Here it is possible to enable TUN interface logging or IPv6 protocol on the VPN interface, choose a proxy server port or Internet protocol version that should be used.
