Expected Behavior

When AdGuard and AdGuard VPN both are installed on device, and AdGuard is using some proxy, and AdGuard VPN updates AdGuard must not disable the proxy.

Actual Behavior

I have AdGuard and AdGuard VPN (v1.0.1 pre-alpha 1 (265)) on my device.
My AdGuard is using proxy (Shadowsocks if that matter), I use AdGuard VPN rarely.
No integration is enabled.

When I update AdGuard VPN from Google Play AdGuard is disabling proxy, and thinks that it is working in integration mode (I suppose).
When I go to proxy settings I see disabled main switch. I enable it - it complains about integration to break, I confirm the dialog, and (I think it send me back in settings) I need to reenter proxy settings screen to enable it the second time.

IMO, when "integration mode" is explicitly disabled in AdGuard (or AdGuard VPN fwiw), this setting should be persisted and cannot be restored unless the user explicitly does that.

yes, i stopped updating the adguard vpn app for this very reason

not only "AdGuard VPN updates AdGuard must not disable the proxy" but AG AB has to just respect the users settings (no matter if whilst updating or in daily use).
Pls see my comments here AdguardTeam/AdGuardVPNForAndroid#113 for why.
