Native settings in SFOS v2.1.0.9 'works', but The direct import of your ovpn file in the settings wizard is broken. But you can set it up by hand:

• Select new vpn session
• Select openvpn
• Do NOT import the ovpn file, skip this step
• Write name of your vpn
• Write whatever in the server adress
• Now, Select the advanced button
• Next, in the field "OpenVPN config file" set the path to your ovpn file.

Thats it, not that you probably should enter full path to certificates in your ovpn file

Me, on the other hand, cant get securefishnet to work.
