hi im using rooted android.If you're using the local VPN option in AG for Android (and you're not rooted) you can only use one VPN at a time as this is a Android OS limitation. If you're rooted, you can enable the local HTTP proxy option which will allow you to use a VPN alongside AG for Android. Otherwise if Outline provides SOCKS proxies you can set that up within AG for Android and use that with the local VPN option.
