It ended up being a day late but better late then never! Here's a link to the post! Please let us know if something doesn't work correctly and we'll update the post accordingly.

@bolly I noticed that as well. The menu area to import the Private Key has None as an option and that's what you should select if using ProtonVPN.

@Lakota I will investigate as soon as I have the time to look into it. My summer has been absolutely packed so far and I barely had time to write tutorial.

I'll report back and ping you with what I find!

I have just made a suggestion on the ProtonMail UserVoice forums for a native Ubuntu Touch application. If you'd like to see this as well, please upvote the suggestion!

I am currently working on a tutorial for setting up VPNs for UT from the .ovpn file that most VPN providers generate for users. The tutorial will be available on the UBports blog on Wednesday so just be monitoring that and if something still isn't working, reply to this thread and I'll see what I can do to help!
