Has Proton added this yet? Most competitors I’ve used always had it. Just go to some url and it will tell you if you’re on Proton.

So far I’ve just been told to check my ip - this is cumbersome and often impractical. I don’t want to break my connection to compare, I’m on my mobile and VPN is on the WiFi router so if I just disconnects from WiFi that will send me to my carrier network so I can’t compare with the WiFi, I may have VPN also on mobile and want to verify that I stay on proton both on and off WiFi, etc.

I think first of all, there should be a clear message when visiting proton sites if I’m on their vpn or not, at least on ProtonVPN, and there should also be a separate url like test.proton.me that tells me just this and is easy to curl etc.
