MultiApp VS PowerTunnel-Android

There is that on Github.

There is this app that allows you to install parallel apps, it works by running the app in a virtualized container https://github.com/WaxMoon/MultiApp

Multi App - run multiple instances of same app

many 3rd party reddit clients have a simple account switch feature built in - i use dawn, but infinity, etc have the feature as well - another option is app-cloning (1+, etc built it into their android, but apps like insular and MultiApp can add the feature if your phone dosnt ship with it)

Multi App: launch multiple same apps at the same time, Run 2 accounts/multi accounts

As for DPI, you could use PowerTunnel or DPITunnel [ROOT]

Pakai Power Tunnel?

Can you try a proxy and see if it works? PowerTunnel

PowerTunnel (version 110): helper against government censorship

unfortunately, it's the only ISP here. they unblocked 1.1.1.1 WRAP for 3 months before they block it again now, I don't know what kind of DPI they are using, but as I heard from PowerTunnel app developer that my ISP uses advanced DPI and he says that chances DPI can be bypassed is very low! now the only protocols that works for me is Stealth in Windscribe app and SSH in Psiphon app nothing works other than that, I have tried tens of VPN apps none of them worked. if they find a way to block SSH and stealth protocols they will do!

assuming you use android and are not rooted you can try using this app, go to setting then change the DNS to cloudflare (the normal one) or something else
