Thanks for providing a free version. Much appreciated. Wish I could pay... hopefully in the future. Unfortunately, it does not work for me on my phone :( postmarketOS on Linux ARM device.

While I lack sufficient experience using the "add-on" to give a quality review of it, I will say that as a subscriber/user of Proton VPN and the services, to which I've been paying for over the past year, have had one or two minor issues, which I have managed to resolve, but aside from that, I am satisfied, and happy with Proton VPN. (So far) I've tried 3 or 4 other (paid) popular VPN services, which I discontinued, after either having issues with their policies and/or after having researched them. Proton is my choice.

При запуске требует "Войти". Окно ввода не открывается. Однако, если запущен другой VPN, окно "Войти" открывается! Зачем нужен этот VPN, который не запустить без другого VPN?!
