All android and iOS apps can see your VPN

If you are using vpn in one profile, then all apps in another profiles can detect 3 your ip’s: 1. Your wifi ip (wlan0 interface) 2. Mobile ip (rmnet0 interface) 3. VPN iP (tun0 interface) So this number after tun/wlan/rmnet may vary, but any app can just try tun0, then try tun1, tun2, etc. There are no limits for them. With 3 those ip’s you can be easy trackable across network.
