It works on iOS, you just have to add the proxy manually via settings.
Could you detail how? Slack/iOS didn't accept my `https://signal.tube/#{redacted}` address in the Proxy Address field. Do I just enter my server's IP address?
I know Android is much more popular in Iran, but I wanted to give my friends instructions for both platforms, just in case.
Oh, lol, you just enter your domain name as the proxy address. Neat! (Or you just click that URL and it bounces you into the Signal app. I assume the only different between the iOS and Android versions here is that the Android version can capture that request before it goes to the browser, which is probably more secure from a government/firewall perspective.)
just a guess, but maybe it has something to do with the fact that the link is never actually handled externally? as in, the signal.tube domain is never resolved, it may as well just be a string
