AdGuard VPN doesn't work with AdGuard Ad Blocker

If you want AdGuard VPN and AdGuard Ad Blocker to work together, check if Compatibility mode is enabled in AdGuard VPN.

Go to Settings → App settings → Advanced settings → Operating mode. Select Compatibility mode with AdGuard.**

You need to enable Compatibility mode only in one of the AdGuard apps: the other app updates automatically.

In Android, you can't run multiple VPN services simultaneously. If you try running another VPN-based app together with AdGuard, it will cause serious problems.
