Can I use a different VPN app along with AdGuard?
Unfortunately, it is impossible to run two VPNs at the same time on Android, but there are some ways to circumvent this limitation. If your device is rooted, or if you only care about blocking ads in WiFi networks, you can switch AdGuard to proxy mode and let any other app to use VPN. Additionally, some VPNs allow the use of upstream proxy (e.g., PIA VPN, Nord VPN) — check if your specific VPN provides this option.
